Antimicrobial studies of stem bark extract and their phytoconstituent from Semecarpus anacardium L
Main Article Content
Abstract
Background & Objective: To investigate the antimicrobial properties of stem bark extract of S. anacardium and
their phytoconstituent using agar well diffusion and in silico docking methods. Methodology: In vitro antibacterial
activity of petroleum ether, chloroform, methanol stem bark extract of S. anacardium was screened against both gram
negative and gram positive bacteria. Results: The methanol extract of stem bark and amentoflavone, a bioactive
compound showed significant antibacterial activity against Klebsiella pneumonia and antifungal activity against
Candida albicans. In silico docking of amentoflavone with bacterial glucosamine-6-phosphate synthase and three
fungal targets, mevalonate-5-diphosphate decarboxylase (1FI4), Sec3 - Rho1 complexes (3A58), Kre2p/Mnt1pa1, 2-
mannosyltransferase (1S4N) showed significant inhibition with minimum binding energy, when compare to standard
drug ciprofloxacin and amphotericin B. Conclusion: This study clearly showed that the amentoflavone used as broad
spectrum of antimicrobial drug
