AB  - In this paper sensitive and selective quantification of the pesticide ziram exploiting its oxidation at a boron doped diamond (BDD) electrode is evaluated. The voltammetric behavior of the pesticide shows in acidic media three well-defined oxidation peaks. For quantification an analytical procedure based on flow injection analysis has been developed. Under optimized experimental conditions a linear dynamic range from 10 to 1000 nM was obtained. The limit of detection (LOD) was estimated to be 2.7 nM. Aftere valuation of effects from possible interferences, the proposed procedure was successfully applied to real samples. (C) 2016 Elsevier B.V. All rights reserved.

AB  - For the first time, a simple and sensitive analytical method for the direct determination of yohimbine is presented using differential pulse voltammetry with a boron-doped diamond electrode. Two irreversible oxidation peaks, a distinct one at +0.80 and a second poorly-defined one at +1.65 V, were observed when cyclic voltammetry was carried out in Britton-Robinson buffer solution at pH 7 (vs. Ag/AgCl). With optimized differential pulse voltammetric parameters (pulse amplitude 100 mV, pulse time 25 ms, step potential 5 mV and scan rate 10 mV s(-1)), the current response of yohimbine at +0.80 V was linearly proportional to the concentration in the range from 0.25 to 90.9 mu mol L-1 with a low detection limit of 0.13 mu mol L-1 (0.046 mg L-1) and a good repeatability (relative standard deviation of 2.5% at 18.4 mu mol L-1 for n = 6). The practical applicability of the developed method was demonstrated by the assessment of the total content of yohimbine in extracts of the primary bark of natural aphrodisiacs such as Pausinystalia yohimbe and Rauvolfia serpentina with recoveries in the range of 92-97%. The proposed electrochemical procedure represents an inexpensive and effective analytical alternative for the quality control analysis of products containing yohimbine and other biologically and structurally related alkaloids used as natural dietary supplements.
