Phytochemical analysis and antimicrobial activity of the ethanolic extract of Acorus calamus rhizome.

Abstract

The present study is aimed at evaluating the in vitro antimicrobial activity of ethanolic extracts of the medicinal plant Acorus calamus against three bacterial (Pseudomonas sp., Bacillus sp., Staphylococcus aureus) and three fungal (Asergillus niger, Aspergillus flavus, Trichoderma sp.) species. The ethanolic extract of Acorus calamus exhibited antimicrobial activity moderately on Pseudomonas sp., Staphylococcus aureus, and Aspergillus flavus. The phytocompounds that are present in the rhizomes of Acorus calamus was screened by Gas Chromatography and Mass Spectroscopy (GCMS) method. The GC-MS study revealed about 10 active phytocompounds present in the rhizomes including alkaloids, aromatic, Palmitic and linoleic acid.
