AB  - Humulones and iso-humulones are potent natural antioxidants found in beer. In this study, density functional theory (DFT) method was applied for elucidating the structure-antioxidant activity relationship and molecular mechanism of antioxidant activity of eight bioactive humulones previously identified in different beer samples: isoxanthohumol, (R)- and (S)-adhumulone, cis- and trans-iso-adhumulone, cis- and trans-iso-n-humulone, and desdimethyl-octahydro-iso-cohumulone. The calculated bond dissociation enthalpies (BDEs) suggest that desdimethyl-octahydro-iso-cohumulone was the most potent compound with BDEs 5.1 and 23.9 kJ/mol lower compared to the values for resveratrol in gas phase and water, respectively. The enolic –OH is the most reactive site for hydrogen atom transfer (HAT). The presence of β-keto group with respect to enolic –OH diminishes the HAT potency via the formation of a strong intramolecular hydrogen bond. Another common antioxidant mechanism, single electron transfer followed by proton transfer (SET-PT), is only feasible for isoxanthohumol. The results of this study indicate a strong correlation between the increased antioxidant activity of beer products and the higher content of reduced iso-α-acids.

AB  - Antibacterial and antibiofilm efficacy through a synergistic effect of herbal leaf extracts of bearberry (BE), bearberry tea (BTE), parsley (PE), and the strawberry tree (STE) was evaluated to discover an alternative approach to control urinary tract infections caused by Enterococci. UHPLC–DAD MS/MS analysis indicated that herbal extracts were rich in ellagic and gallic acids, catechin, quercetin, and arbutin, which are strong antioxidants. Mostly, Enterococcus faecalis isolates showed resistance only to gentamicin and/or norfloxacin (26.3 %) and moderate biofilm production (31.5 %), while 12 isolates of Enterococcus faecium showed multiple antibiotic resistance. The minimum inhibitory concentration for the majority of isolates was 1.25 mg ml−1 for STE, but 2.5 mg ml−1 for BE and BTE. Although individual extracts gave higher MIC values, for most isolates, a synergistic effect at lower concentrations was achieved, when BE or BTE (0.625 mg ml−1) was combined with STE (0.31 mg ml−1). The BTE extract was shown to have the strongest individual effect on initial adhesiveness and on biofilm formation to all selected isolates, while the synergism of BTE and STE caused significant biofilm inhibition at all concentrations tested. The synergistic effect achieved of the tested extract combinations might be a starting point in the development of alternative products, effective against antibiotic resistant Enterococcus isolates.

AB  - Phytochemical analysis, the chemical investigation of plants, is a rapidly developing chemical discipline with various goals such as the determination of the substance classes and the isolation and qualitative and/or quantitative analyses of bioactive compounds or their structural analysis. The analysis of plants begins with optimizing extraction procedures because they play a key role in extraction outcomes, i.e., the isolation of bioactive compounds from natural products and the selection of the subsequent tests used in the analyses. The extraction is a critical step because it is necessary to extract the desired components of the complex natural matrix without destroying them. A wide range of techniques for the extraction of bioactive compounds from natural matrixes are currently available. This review aims to describe and compare the most commonly used methods, traditional/conventional and innovative/green. It will focus on the principles behind each method and on their strengths and limitations in order to help evaluate their suitability and economic feasibility, highlighting the advantages of new innovative techniques over conventional extraction procedures. Finally, the recent application of deep eutectic solvents as a new, eco-friendly method for the extraction of bioactive compounds from natural matrixes is also discussed.

AB  - Linden tea has been used in Serbian folk medicine for centuries to induce sweating for colds, relieve throat irritation and cough, reduce blood pressure, as well as a diuretic, spasmolytic, and as a sedative. The main aim of this study was to determine the comprehensive metabolite profile, free radical scavenging activity, and antimicrobial activities against 23 human and plant pathogens of both commercial and field-collected linden tea samples from Serbia. Developed high-performance thin-layer chromatography (HPTLC) method allowed identification of eight major metabolites in investigated samples, while forty-six metabolites were tentatively identified using high resolution mass spectrometry (HRMS): 14 phenolic acids and their derivatives, 15 glycosides, 9 flavonoids, and 8 procyanidins. Both commercial and field-collected linden tea samples showed similar total phenolic content and radical scavenging activity. Seven compounds such as p-hydroxybenzoic acid 4-O-hexoside, caffeic acid cinnamyl ester, pinocembrin, galangin, luteolin 7-O-glucuronide (and its isomer), isorhamnetin hexosyl hexoside were found in Tilia samples for the first time. Radical reagent 2,2-Diphenyl-1-picrylhydrazyl· (DPPH·) was used in DPPH-HPTLC assay which identified chlorogenic acid, caffeic acid, astragalin, quercitrin, tiliroside, and rutin as compounds that exhibit radical scavenging activity. Tilia samples showed inhibitory effect overwhelming only on Gram-positive bacteria, especially on Bacillus subtilis with the lowest MIC values observed, as well as towards Staphylococcus aureus and oral cavity isolates of Streptococcus pyogenes and Streptococcus mutans. Vaginal isolate of Candida glabrata showed more susceptibility than Candida albicans isolate. Generally, extract from Tilia cordata Miller (L4) showed the highest antimicrobial activity against the most of the tested pathogens, among all field-collected Tilia samples.

AB  - Ethnobotanical and ethnopharmacological studies of many Centaurea species indicated their potential in folk medicine so far. However, investigations of different Centaurea calcitrapa L. extracts in terms of cytotoxicity and antimicrobial activity against phytopathogens are generally scarce. The phenolic profile and broad antimicrobial activity (especially towards bacterial phytopathogens) of methanol (MeOH), 70% ethanol (EtOH), ethyl-acetate (EtOAc), 50% acetone (Me2CO) and dichloromethane: methanol (DCM: MeOH, 1: 1) extracts of C. calcitrapa leaves and their potential toxicity on MRC-5 cell line were investigated for the first time. A total of 55 phenolic compounds were identified: 30 phenolic acids and their derivatives, 25 flavonoid glycosides and aglycones. This is also the first report of the presence of centaureidin, jaceidin, kaempferide, nepetin, flavonoid glycosides, phenolic acids and their esters in C. calcitrapa extracts. The best results were obtained with EtOAc extract with lowest MIC values expressed in µg/mL ranging from 13 to 25, while methicillin resistant Staphylococcus aureus was the most susceptible strain. The most susceptible phytopathogens were Pseudomonas syringae pv. syringae, Xanthomonas campestris pv. campestris and Agrobacterium tumefaciens. The highest cytotoxicity was recorded for EtOAc and Me2CO extracts with the lowest relative and absolute IC50 values between 88 and 102 µg/mL, while EtOH extract was the least toxic with predicted relative IC50 value of 1578 µg/mL. Our results indicate that all tested extracts at concentration considered as non-toxic can be one of great importance in combat towards phytopathogenic and human pathogenic strains, as well as natural sources of antimicrobials.

AB  - Aims: A multidisciplinary approach was used to compare phenolic composition, radical scavenging and antimicrobial activity of propolis samples from different geographical localities, and plant resin against various microorganisms. Methods and Results: Using UHPLC-qqqMS quantitative analysis, 28 phenolic compounds were determined. Caffeic and p-coumaric acids were identified as main phenolic acids in poplar propolis samples, except samples from Russia (P6) and China (P7). Radical scavenging activity (applying DPPH spectrophotometric assay) showed the highest activity of Serbian (40·51%) and Chinese (53·21%) propolis samples. Broth microdilution method was used for the oral cavity, fungal phytopathogenic and human vaginal isolates which have been identified at a molecular level. The most sensitive bacterial isolates were Lactobacillus acidophilus (MIC of 0·03–0·13 mg ml−1) and the oral streptococci isolates (MIC values of 0·19–0·13 mg ml−1). The most sensitive fungal phytopathogenic isolate was Fusarium oxysporum (MIC 0·003 mg ml−1). All samples, except propolis from Serbia (P4) and Turkey (P5), showed a strong antifungal activity against Fusarium sporotrichioides, Fusarium subglutinans and Fusarium proliferatum. Conclusion: The results of various tests indicate good radical scavenging and antimicrobial activity against important human and plant pathogens. Significance and Impact of the Study: A detailed propolis analysis is important when proposing a preparation of new biological antimicrobial products which have a positive impact on human health and reduce antibacterial resistance.

AB  - Essential oils are highly volatile, aromatic concentrated extracts from plants with wide applications. In this study, fast, easy-to-use attenuated total reflection Fourier-transform infrared spectroscopy (ATR-FTIR) was combined with chemometric techniques to verify essential oils’ taxonomy and purity. Principal component analysis (PCA) clustered 30 essential oil samples into three different groups based on plant botanical family and concentration. The first group contained highly concentrated oils from the Asteraceae family, the second group contained highly concentrated oils from the Lamiaceae family, while the last group contained three highly concentrated essential oils from different botanical families and commercial-grade essential oils. Thus, commercial-grade oil samples did not cluster with the corresponding concentrated oil samples despite their similar spectral patterns or botanical family. A loading plot identified infrared (IR) bands that correspond to carbonyl, vinyl, methyl and methylene group vibrations as the most important spectral bands that can be used as marker bands for discrimination between different botanical plant family groups. Hierarchical cluster analysis (HCA) confirmed the results obtained by PCA. ATR-FTIR spectroscopy combined with chemometric algorithms provides a direct and non-destructive method for chemotaxonomic classification of medicinal and aromatic essential oils and an assessment of their purity.

AB  - Bivalve molluscs, which include mussels, oysters and clams, have high nutritional value. They are regarded as a good source for proteins, lipids, carbohydrates and minerals [1]. On the other hand, seafood may also contain harmful contaminants and other undesirable substances such as mercury and persistent halogenated compounds, which has resulted in a number of risk-benefit assessments during the last decade [2].
Four species of bivalve molluscs Ruditapes philippinarum (Manila clam, MC), Yesso scallop (YS), Tegillarca granosa (TG) and Anadara broughtonii (AB) were bought in two fish markets in Incheon, Korea, in order to determine content of As, Cd, Co, Cr, Cu, Hg, Mn, Ni, Pb, Se, Zn, and Fe and consequently, to estimate the health hazards associated to dietary intake. The samples were analyzed by inductively coupled plasma mass spectrometry (ICP-MS) after closed-vessel microwave digestion. The analytical accuracy of the method was evaluated by using the SRM (TORT-2, lobster hepatopancreas). Application of principal component analysis (PCA) and hierarchical cluster analysis (HCA) showed a tendency to form three groups between samples belonging to different genus of samples.
European food safety authority (EFSA) has established recommended daily intake (RDI) values for Cu, Fe, Mn and Zn of 3, 14, 5 and 10 mg/day, respectively. We calculated the RDI for daily consumption in milligrams per 300 g of sample. Our results showed that these species could serve as a good dietary source of essential elements, especially Fe, Mn and Zn. However, all species showed As content higher than the maximum tolerable limit specified by EFSA. Seafood is the major contributor to As in the diet though As in seafood mostly occurs as organic As species [3]. In addition, content of Mn in Yesso scallop is few times higher than in other species.

AB  - Consumption of bivalve molluscs, such as oysters, mussels, clams and scallops, makes a significant part of the daily Korean diet. Bivalves provide high quality proteins with all the dietary-essential amino acids, lipids, vitamins, minerals and other bioactive nutrients, which offer a variety of health benefits to the consumer [1]. This food contains less than 5 percent of total fat, so it is considered a low-fat food. Beside the amount of total fat, the proportions of saturated, monounsaturated and polyunsaturated fatty acids (FA) (S, M and P, respectively), as well as ratio of n-3 (ω-3) and n-6 (ω-6) P in food are very important for the health diet [2].
Fourteen species of bivalves Anadara broughtonii (AB), Ruditapes philippinarum (Manila clam (RP)), Tegillarca granosa (TG), Pecten yessoensis (Yesso scallop (YS), Argopecten spp. (small scallop (SS), Chlamys farreri farreri (CF), Cyclina sinensis (CS), Leukoma jedoensis (LJ), Mytilus califorianus (MCa) Mytilus galloprovancialis (MG), Maretrix lusoria (ML), Mactra quadrangularis (MQ), Sinovacula constricta (SC) and Crassostrea gigas (Pacific oyster (PC)) were bought in two fish markets in Incheon, Korea, in order to determine FA composition using GC/EI-MS of fatty acid methyl esters (FAME). The FAME were identified by comparing their retention times with those of the FAME standards or by comparing their mass spectra with those stored in the NIST Mass Spectral Library.
In the bivalve samples, 43 different FA were identified, of which 10 were S, 12 M and 13 P, other FA were 7 methyl-FA and 1 hydroxyl-FA. The P/S ratio and ω-6/ω-3 P ratio are the most significant markers of lipid composition in a healthy diet and both should be close to 1 [3]. Among analysed species, only YS and SS have P/S ratio close to 1 (1,20 and 1.16, respectively), while other species have value between 0.07 and 0.73. The obtained values for ω-6/ω-3 P ratio were from 0.008 to 0.55, which indicates that bivalve molluscs are the valuable source of ω-3 P (EPA and DHA). These ω-3 P play important roles in growth, development, and maintenance of health.

AB  - Bacillus species produce a wide array of biologically active metabolites, including nonribosomaly synthesized lipopeptides (LPs). The high-performance thin-layer chromatography (HPTLC) technique hyphenated with different bioassays and mass spectrometry was demonstrated as a valuable tool for effect-directed analysis of iturins, surfactins, fengycins and kurstakins homologues from complex mixtures of LPs. As proof of this straightforward strategy, the found surfactin and iturin A homologues were characterized and compared with reference substances. This study considered two different extraction methods for LPs produced by five Bacillus strains. The ethyl acetate extraction (Ex-1), and the acidic precipitation followed by methanol extraction (Ex-2) were investigated. Diverse enzyme inhibitions and antimicrobial potentials of LPs were analyzed, and in parallel, high-resolution mass spectra (HRMS) were online recorded from the HPTLC zones of interest. No antimicrobial effect against Gram-positive B. subtilis was evident for iturin, whereas a response was detected for surfactin. The nonpolar kurstakin compounds showed a pronounced B. subtilis antimicrobial activity in Ex-1 of almost all strains, whereas the fengycin homologues were detected in Ex-2 of SS-10.7 and SS-27.2. Iturin had also no activity against Gram-negative Aliivibrio fischeri, while again surfactin showed an enhancing luminescent activity. Contrary, kurstakin compounds caused a decrease in the luminescence in Ex-1 of all strains, particularly for SS-13.1. Both, iturin and surfactin showed a strong acetylcholinesterase (AChE) and α-glucosidase inhibition, but surfactin caused a much stronger inhibition. This was evident in all bacterial strains, except for SS-13.1 in Ex-1 and for SS-38.4 in Ex-2. Although, iturin and surfactin exhibited no DPPH˙ scavenging activity, Ex-1 of all strains contained more intense DPPH˙ scavenging compounds compared to Ex-2, and surfactin methyl esters showed a pronounced DPPH˙ activity, particularly in SS-12.6 in Ex-1. This study pointed to active metabolites of strains that can be used as therapeutics and biocontrol agents with beneficial effects on human health. The straightforward HPTLC profiling served as an excellent bioanalytical tool to control the formed bioactive metabolites. As the fermentation process is very sensitive to external influences, it could be a helpful control tool for standardization of the biotechnological processing.

AB  - Quality control is a crucial step in the production of effective and safe herbal remedies. The aim of this study was to develop a new, simple, and high throughput procedure for the quality assessment of herbal drugs using a high-performance thin-layer chromatography (HPTLC)/bioautography and UPLC–MS/MS approach combined with chemometrics. This was exemplarily shown for Morus alba L. root bark (sāng bái pí; SBP). Bioautography assays were developed for the identification of constituents with radical scavenging (DPPH assay) and antimicrobial activities (Bacillus subtilis, Escherichia coli) of 18 different M. alba samples, which was supported by UPLC–MS/MS analysis. Further, the combination of bioautography and chemometrics identified those samples with the most bioactive constituents. Plant materials collected from Serbia (11 samples) showed higher both radical scavenging and antimicrobial activities compared to samples provided from China (7 samples). Principal component analysis (PCA) confirmed the discrimination of geographically different samples and recognized their main markers responsible for differences between Serbian and Chinese samples. Most importantly for quality assessment, the combined HPTLC/bioautography and UPLC–MS/MS approach not only allowed for a fast chemical profiling of the investigated samples and their unambiguous identification, but also for the disclosure of major and minor bioactive constituents present in SBP.

The aim of this study was to develop a new, simple, and high throughput procedure for the quality assessment of herbal drugs using a high-performance thin-layer chromatography (HPTLC)/bioautography and UPLC–MS/MS approach combined with chemometrics. This was exemplarily shown for Morus alba L. root bark (sāng bái pí; SBP). Bioautography assays were developed for the identification of constituents with radical scavenging (DPPH assay) and antimicrobial activities (Bacillus subtilis, Escherichia coli) of 18 different M. alba samples, which was supported by UPLC–MS/MS analysis. Further, the combination of bioautography and chemometrics identified those samples with the most bioactive constituents. Plant materials collected from Serbia (11 samples) showed higher both radical scavenging and antimicrobial activities compared to samples provided from China (7 samples). Principal component analysis (PCA) confirmed the discrimination of geographically different samples and recognized their main markers responsible for differences between Serbian and Chinese samples.

AB  - The quality of three types of beer (dark, light and non-alcoholic) was assessed using high-performance thin-layer chromatography (HPTLC) combined with high-resolution mass spectrometry and chemometrics. An HPTLC separation of the polar beer components in the ethyl acetate extract was developed. The polar components were detec ted either by the in situ 2, 2 -d iphenyl -1-picrylhydrazyl (DPPH*) assay or by derivatization with the Neu’s reagent, followed by the PEG solution. This directly allowed the visual comparison and evaluation of the phenolic/flavonoid or radical scavenging (antioxidative) beer profile. Although the three types of beer showed a very similar chemical HPTLC pattern, the signal intensities were different. Detected by the Neu’s reagent, the dark beer extracts contained a high amount of phenolic compounds, and the light beer extracts showed a moderate content, while the non-alcoholic beer extracts had the lowest phenolic content. The HPTLC—DPPH* assay confirmed the higher radical scavenging activity of dark beer extracts, if compared to light and non-alcoholic beer extracts. The most active bands with regard to the radical scavenging property were identified to be desdimethyl-octahydro-iso-cohumulone and iso-n/ad-humulone. The use of pattern recognition techniques showed a clear differentiation between dark and non-alcoholic beer extracts, while light beer extracts did overlap with both beer types. This HPTLC screening allowed the (1) direct comparison of beer samples/types via classification and pattern recognition, (2) the assessment of the beer quality with regard to its antioxidative potential, and (3) the reference to single components.

AB  - Comprehensive analysis of phenolic profiles of botanically different subtypes of Turkish propolis samples were performed using UHPLC-LTQ/Orbitrap/MS/MS method, and additionally total phenolic (TPC) and total flavonoid contents (TFC) as well as their antioxidative activities were evaluated by spectrophotometry. Antimicrobial activity of Turkish propolis against oral cavity bacteria from the genus Streptococcus (S. pyogenes, S. sanguinis, S. mutans) and Candida albicans ATCC 10231 was determined by diffusion and microdilution methods. Extensive fingerprint analysis of Turkish propolis revealed the presence of fifty one phenolic compounds, with fifteen quantified which confirm their affiliation to the two subtypes of the European propolis. All analysed samples have shown antimicrobial potential against all tested bacteria, with S. pyogenes being the most sensitive one. Turkish propolis, especially its orange subtype, can be considered as the high-quality product due to its rich phenolic and flavonoid content, strong antioxidative and antimicrobial activities. Turkish propolis could be, therefore, a good raw material for food and pharmaceutical industry.

abstract = "Comprehensive analysis of phenolic profiles of botanically different subtypes of Turkish propolis samples were performed using UHPLC-LTQ/Orbitrap/MS/MS method, and additionally total phenolic (TPC) and total flavonoid contents (TFC) as well as their antioxidative activities were evaluated by spectrophotometry. Antimicrobial activity of Turkish propolis against oral cavity bacteria from the genus Streptococcus (S. pyogenes, S. sanguinis, S. mutans) and Candida albicans ATCC 10231 was determined by diffusion and microdilution methods. Extensive fingerprint analysis of Turkish propolis revealed the presence of fifty one phenolic compounds, with fifteen quantified which confirm their affiliation to the two subtypes of the European propolis. All analysed samples have shown antimicrobial potential against all tested bacteria, with S. pyogenes being the most sensitive one. Turkish propolis, especially its orange subtype, can be considered as the high-quality product due to its rich phenolic and flavonoid content, strong antioxidative and antimicrobial activities. Turkish propolis could be, therefore, a good raw material for food and pharmaceutical industry.",

AB  - Propolis is a honeycomb product having very diverse chemical composition and possessing a broad spectrum of biological activities. This study comprehensively evaluated the phenolic profile of Turkish propolis by using a high performance thin-layer chromatographic (HPTLC) method in combination with image analysis and pattern recognition technique. Also, botanical origin of each propolis sample was determined by comparison of HPTLC fingerprints of propolis samples with that of plant bud extracts and also by palynological analysis. Moreover, HPTLC coupled with 2,2-dipheny1-1-picrylhydrazyl (DPPH) detection technique was used for screening of antioxidant activity of each separated compounds directly on the plate. Results of the present study have demonstrated that Turkish propolis could be classified under three main types; i.e. orange (O) (originated from Populus nigra L), blue (B) (originated from Populus tremula L) and nonphenolic types. Palynological analysis have shown that dominant pollen grains ( gt %45) in propolis samples were: Fabaceae, Lamiaceae, Rosaceae, Castanea sativa Mill., Lotus corniculatus L., Salix spp. In addition, HPTLC-DPPH results showed that O-type of propolis exerted higher antioxidant activity than the other propolis types. Moreover, quercetin, caffeic acid, caffeic acid phenyl ester, pinobanksin and galangin had significant contribution to the antioxidant activity of propolis. (C) 2017 Elsevier Ltd.

AB  - Biological and biochemical fingerprints were investigated for the first time for the feasibility of effect-directed classification, and thus, to allow the choice of a distinct beer with regard to beneficial health effects. A high-performance thin-layer chromatography method was newly developed and combined with in situ effect-directed analysis for profiling 50 German beers for multipotent active compounds, and thus, their health-related potential. Discovered multipotent active zones were online eluted and characterized by high resolution mass spectrometry. For example, isoxanthohumol, iso-α-ad/n-humulone or its isomers, desdimethyl-octahydro-isocohumulone and ad/n-humulone were proven as antimicrobial compounds, isoxanthohumol as an acetylcholinesterase inhibitor, and isoxanthohumol and iso-α-ad/n-humulone or its isomers as radical scavengers. Investigating multivariate data analysis of effect-directed fingerprints for the first time, the pattern recognition and classification results showed the power of clustering non-alcoholic beers from other types of beer, or it showed the differentiation of dark and non-alcoholic beers. © 2018 Elsevier Ltd

AB  - Ethnopharmacological relevance: Trapa natans L. (water chestnut or water caltrop) is a widespread aquatic plant, which has been cultivated for food and traditional medicine since ancient times. Pharmacological studies showed that water chestnut exhibits the wide range of biological activities, such as antimicrobial, antioxidative, analgesic, anti-inflammatory, as well as antiulcer. Aim of the study: Evaluation of anti-virulence potential and toxicity of T. natans methanol (TnM), acetone (TnA) and ethyl acetate (TnEA) leaf extracts. Materials and methods: The anti-quorum sensing activity of Tn extracts was addressed by measuring their effects on biofilm formation, swarming motility and pyocyanin and elastase production in Pseudomonas aeruginosa. Specific P. aeruginosa biosensors were used to identify which of the signaling pathways were affected. The lethal and developmental toxicity of extracts were addressed in vivo using the zebrafish (Danio rerio) model system. The phenolic composition of T. natans leafs extracts was analyzed by a linear ion trap-OrbiTrap hybrid mass spectrometer (LTQ OrbiTrapMS) and UHPLC system configured with a diode array detector (DAD) hyphenated with the triple quadrupole mass spectrometer. Results: Subinhibitory concentrations of Tn leaf extracts (0.2 MIC) inhibited pyocyanin and elastase production up to 50% and 60%, respectively, and reduced swarming zones, comparing to non-treated P. aeruginosa. TnA inhibited biofilm formation by 15%, TnM showed a stimulatory effect on biofilm formation up to 20%, while TnEA showed no effect. The bioactive concentrations of TnM and TnA were not toxic in the zebrafish model system. Twenty-two phenolic compounds were tentatively identified in TnM, where thirteen of them were identified in T. natans for the first time. Tn extracts, as well as their major components, ellagic and ferulic acids, demonstrated the ability to interfere with P. aeruginosa Las and PQS signaling pathways. Conclusions: This study demonstrates anti-virulence potential of Tn leaf extracts against medically important pathogen P. aeruginosa and confirms the ethnopharmacological application of this plant against microbial infections.
