Analysis and preparation of phenolic and alkaloid compounds from Moroccan Berberis vulgaris organic extract: Molecular docking and optimization by UHPLC/DAD/ESI-MS

Among the natural products, phenolic and alkaloid compounds have the most important constituents and common plant-derived secondary metabolites, and thus, analysis deserves particular attention for their therapeutic proprieties. In this study, the phenolic and alkaloid compounds were analyzed using ultra-high-performance liquid chromatography coupled with diode array detector-tandem electrospray ionization mass spectrometry (UHPLC/DAD/ESI-MS) for three extracts of Moroccan Berberis vulgaris L. Then we optimized and validated results for four phenolic compounds. To evaluate the biological activity of this species we chose the antimicrobial activity. For the antimicrobial activity of these extracts, we used molecular docking analysis of the compounds identified with DNA gyrase. The method validation results showed a good linear (R۲>۰.۹۹) with the coefficient correlation and the significance of regression tests confirmed a linear relationship between x and y. Two concentrations of phenolic and alkaloid compounds (۳۱.۲۵ mg L-۱ and ۵۰۰ mg L-۱) were determined by the UHPLC/DAD/ESI-MS and used in repeatability tests, the relative standard deviation of ۱۰ repetitions varied to ۰.۳۵-۲.۳۳ with CV% ۱.۱-۲%. In addition, the analytical method is sensitive, accurate, and precise (CV<۵%). The analytical method successfully set for robust quality evaluation and standardization of phenolic and alkaloid compounds from B. vulgaris organic extract.
