AB  - Due to the promising applications of propolis as a natural food preservative, functional ingredient or supplement, on one side, and the inherent toxicity and high volatility of organic solvents used for extraction of phenolics from propolis, a range of natural eutectic solvents (NESs) was evaluated for the extraction of phenolic compounds from poplar type propolis to create “green-labelled” food products. The phenolic profile of novel green propolis extracts was evaluated using high-performance thin-layer chromatography, while 16 phenolic compounds were quantified by ultra-high-performance liquid chromatography hyphenated with mass spectrometry. Pinocembrin and chrysin were the most dominant phenolics with an average concentration of 3111 and 3039 mg/kg in lactic acid-based NES, respectively. Biological activity, such as antioxidative and antimicrobial activities, were determined using spectrophotometric and well diffusion methods. Considering all spectrophotometric assays lactic acid-based presented as the best extraction medium for phenolic extraction, with TPC, TFC and RSA values 150.0 mg GAE/g, 190.0 mg RUE/g, and 132.8 mg TE/g on average, respectively. From 38 studied NESs, choline-chloride:tartaric acid (1:1 n/n), glycerol:lactic acid (1:1 n/n) and glycine: lactic acid (1:3 n/n) were the most promising extraction medium for obtaining the propolis extracts enriched with bioactive compounds. Additionally, proposed green solvents were proved to be the designer solvents and showed potential to be tuned to target specific phenolic compounds. Improved, or at least maintained, biological activity of NES propolis extracts support its application in agriculture industry.

AB  - The present study provides, for the first time, a physicochemical and biochemical characterization of the redox processes associated with the ripening of Solanum dulcamara L. (bittersweet) berries. Electron Paramagnetic Resonance Spectroscopy (EPRS) and Imaging (EPRI) measurements of reactive oxygen species (ROS) were performed in parallel with the tissue-specific metabolic profiling of major antioxidants and assessment of antioxidant enzymes activity. Fruit transition from the mature green (MG) to ripe red (RR) stage involved changes in the qualitative and quantitative content of antioxidants and the associated cellular oxidation and peroxidation processes. The skin of bittersweet berries, which was the major source of antioxidants, exhibited the highest antioxidant potential against DPPH radicals and nitroxyl spin probe 3CP. The efficient enzymatic antioxidant system played a critical protective role against the deleterious effects of progressive oxidative stress during ripening. Here, we present the EPRI methodology to assess the redox status of fruits and to discriminate between the redox states of different tissues. Interestingly, the intracellular reoxidation of cell-permeable nitroxide probe 3CP was observed for the first time in fruits or any other plant tissue, and its intensity is herein proposed as a reliable indicator of oxidative stress during ripening. The described noninvasive EPRI technique has the potential to have broader application in the study of redox processes associated with the development, senescence, and postharvest storage of fruits, as well as other circumstances in which oxidative stress is implicated.

AB  - DES are mixtures of a hydrogen bond donor (HBD) and a hydrogen bond acceptor (HBA) that, when combined in a specific molar ratio, exhibit a significant decrease in melting point and become liquid at room temperature. DES can be tailored to meet different physicochemical requirements by altering the HBA:HBD ratio or the nature of the compounds. In this study, we utilized the COSMO-RS method to predict the activity coefficients of 12 phenolic compounds in 105 NaDES. These NaDES contained equimolar mixtures of betaine, carnitine, creatine, and ornithine as HBAs and various sugars and amino acids as HBDs. The NaDES were compared to methanol, and several mixtures exhibited higher affinities to all phenolics. The most promising NaDES were betaine-glycerol, betaine-xylitol, and carnitine-urea. We are currently conducting experimental validation of the extraction efficiency of these cosmetically acceptable solvents. In summary, we have identified promising NaDES mixtures that could replace conventional solvents and contribute to the development of sustainable, bio-based extracts.

AB  - The latest studies show that UV and blue light, emitted by electronic devices with screens, slows the proliferation of the keratinocytes and generates free radicals leading to skin ageing1. Polyphenols, a compounds found in plants, can prevent light-induced damage to the skin. A constant screening of plant extracts is requisite in order to discern light-protective formulations to constitute cosmetic products. Using mass spectrometry, phenolic compounds were identified and quantified in plant extracts from 18 plants grown in Eastern Serbia. The cytotoxicity of the obtained extracts was tested on HaCaT cells (immortalized human keratinocytes) and IC50 values were determined. The obtained extracts are rich mixtures of phenolic compounds that must be dosed appropriately since they also damage skin cells at larger concentrations.

AB  - Due to their strong antioxidative potential, flower petals are considered important starting materials for the development of cosmetic products1. Present study explored phenolic profile and antioxidative potential of 17 flower petals and their potential application in the cosmetics industry. The phenolic profile of investigated extracts was determined using High-Performance Thin Layer Chromatography (HPTLC). The antioxidative potential was assessed using both ABTS and DPPH spectrophotometric tests, and total phenol content. DPPH-HPTLC assay was applied to identify compounds with the highest antioxidative activity. Five phenols were identified in the investigated extracts. Based on radical antioxidative tests, Paeonia lactifora, Paeonia decora, Rosa istriaca and Pelargonium peltatum were identified as species with the highest antioxidative potential, while gallic acid was recognized as the strongest antioxidants.

AB  - The cosmetic industry is currently experiencing substantial growth, accompanied by a surge in the number of consumers. Due to natural ingredients' safety and efficiency, an increasingly prominent trend in this industry is the design of herbal-based cosmetic products and formulations. To meet demand, integrating innovative natural resources like plant-based formulations is essential [1]. Skin ageing-related enzymes, elastase and tyrosinase, contribute to the emergence of aesthetic issues such as wrinkles, freckles, and loss of elasticity, as well as hyperpigmentation and melasma [2]. Hence, there is an increasing focus on finding inhibitors for enzymes associated with skin ageing. The fact is that plant metabolites, particularly phenolic acids and flavonoids, are frequently concentrated in plant leaves and flowers. Accordingly, we assessed the inhibitory effects on elastase and tyrosinase in seventeen particularly selected methanolic extracts obtained from various flower petal varieties cultivated in Serbia. Our analysis revealed that petals exhibit significantly more pronounced inhibitory effects, expressed as IC50 values, on elastase compared to tyrosinase. White peony (Paeonia lactifora) (230 ± 1 μg/mL), pelargonium (Pelargonium peltatum) (206 ± 3 μg/mL) and purple rose (Rosa centifolia, purple) (222 ± 8 μg/mL) emerged as the most potent elastase inhibitors, surpassing the reference compound epigallocatechin gallate (348 ± 9 μg/mL). Additionally, the lowest IC50 value for tyrosinase inhibition was attributed to lilac (Syringa vulgaris) petal extract (272 ± 28 μg/mL), which was compared to the standard compound kojic acid (50 ± 14 μg/mL). In conclusion, white peony, pelargonium, purple rose, and lilac represent promising candidates for further investigation and incorporation into cosmetic products, showcasing their potential to effectively address skin-related concerns.

abstract = "The cosmetic industry is currently experiencing substantial growth, accompanied by a surge in the number of consumers. Due to natural ingredients' safety and efficiency, an increasingly prominent trend in this industry is the design of herbal-based cosmetic products and formulations. To meet demand, integrating innovative natural resources like plant-based formulations is essential [1]. Skin ageing-related enzymes, elastase and tyrosinase, contribute to the emergence of aesthetic issues such as wrinkles, freckles, and loss of elasticity, as well as hyperpigmentation and melasma [2]. Hence, there is an increasing focus on finding inhibitors for enzymes associated with skin ageing. The fact is that plant metabolites, particularly phenolic acids and flavonoids, are frequently concentrated in plant leaves and flowers. Accordingly, we assessed the inhibitory effects on elastase and tyrosinase in seventeen particularly selected methanolic extracts obtained from various flower petal varieties cultivated in Serbia. Our analysis revealed that petals exhibit significantly more pronounced inhibitory effects, expressed as IC50 values, on elastase compared to tyrosinase. White peony (Paeonia lactifora) (230 ± 1 μg/mL), pelargonium (Pelargonium peltatum) (206 ± 3 μg/mL) and purple rose (Rosa centifolia, purple) (222 ± 8 μg/mL) emerged as the most potent elastase inhibitors, surpassing the reference compound epigallocatechin gallate (348 ± 9 μg/mL). Additionally, the lowest IC50 value for tyrosinase inhibition was attributed to lilac (Syringa vulgaris) petal extract (272 ± 28 μg/mL), which was compared to the standard compound kojic acid (50 ± 14 μg/mL). In conclusion, white peony, pelargonium, purple rose, and lilac represent promising candidates for further investigation and incorporation into cosmetic products, showcasing their potential to effectively address skin-related concerns.

AB  - Excess of free radicals in skin causes oxidative stress, which results to skin aging and
appearance of age spots. The enzyme tyrosinase is responsible for mentioned process.
Slowing down of this unwanted process is one of the challenges of modern science. Thus,
the aim of this study is to examine the potential of selected plant extracts to reduce
oxidation stress and the appearance of hyperpigmentation. The extracts were characterized
by the use of high-performance thin-layer chromatography and high-performance liquid
chromatography coupled with mass spectrometry. The antioxidant activity of the extracts
and potential for the inhibition of tyrosinase enzyme were determined. Nineteen phenolic
compounds were quantificated in the tested extracts. The obtained results demonstrate that
the extracts of Morus alba (92%), Rubus (86%) and Agrimona eupatoria (84%) are the
most effective inhibitors. The Teucrium chamaedrys and Agrimona eupatoria showed high
values of antioxidant activity. The listed samples are commercial.

AB  - Propolis is a resinous substance collected by honeybees (Apis mellifera L.) from
different plant parts such as branches, plant buds, leaves, and exudates partially digested
by β-glycosidase from bees’ saliva, and after that mixed with beeswax. It is commonly
used in folk medicine to prevent and treat colds, ulcers, rheumatism, diabetes, and dental
caries. Commercially available products most often comprise ethanolic extracts of
propolis. However, high alcohol content and strong residual flavour make such products
unsuitable for patients intolerant to alcohol, especially children. Due to mentioned
drawbacks, propylene glycolic, aqueous, fructose, or olive oil propolis extracts are
commonly found on the market as safer alternatives. These solvents are more appealing
options but the extraction efficiency is up to 10 times lower compared to ethanol. Thus,
there are high demands for the development of effective and ethanol-free extractions1,2
.
The overall aim of the study is to determine total phenolic, flavonoid content and radical
scavenging activity of high-quality and natural-based propolis extract enriched with
bioactives using new generation of solvents as Natural Deep Eutectic Solvents
(NADES)1
. Thirty-eight different green NADES have been used for the extraction of
phenols from poplar types of propolis. The NADES were prepared by mixing different
molar ratios of polycarboxylic acids, amino acids, glycerol, urea, potassium acetate,
choline chloride and ethylene glycol. The highest values of TPC, TFC, and DPPH were
obtained using following NADES systems: lactic acid/glycerol=1/1; lactic
acid/glycine=3/1; glycerol/proline=1/1; choline chloride/succinic acid=2/1 and choline
chloride/ethylene glycol=1/4.

AB  - Lekovite biljke predstavljaju neiscrpni izvor biološki aktvinih jedinjenja koja se u većini slučajeva mogu ponašati kao antioksidansi. U okviru ovog rada ispitaivan je profil biljnih metabolita i antioksidativna aktivnost 22 biljke koje se mogu pronaći na teritoriji Republike Srbije. Metaboliti su ekstrahovani iz biljnog materijala ekstrakcijom potpomognutom ultrazvukom upotrebom četiri konvencionalna organska rastvarača. Ispitivana je antioksidativna aktivnost dobijenih ekstrakata u cilju iznalaženja najaktivnijih biljnih ekstrakata dok je tankoslojna hromatografija praćena hemometrijskom analizom upotrebljena u cilju pronalaženja sličnosti među biljnim vrstama koje bi se potencijalno mogle koristiti kao alternativne biljke u kozmetičkoj industriji. Na osnovu dobijenih rezultata zaključeno je da zeleni čaj, petrovac, podubica, iva, glog i origano predstavljaju bogat izvor biološki aktivnih jedinjenja i poseduju izražen antioksidativni potencijal. Takođe, zaključeno je da sistemi rastvarača etanol – voda i metilenhlorid – metanol ekstrahuju jedan tip aktivnih jedinjenja dok metanol ekstrahuje drugačije aktivne supstance iz biljaka, što ukazuje na veliki biološki i hemijski diverzitet ekstrahovanih biljaka.
