ABSTRACT

The present aim is to study of some ethnomedicinal plants having antimicrobial activity and commonly found around the area in different districts of West Bengal, India. Common ethnomedicinal plants from several areas of different districts are collected and tested against Gram +ve and Gram –ve bacteria for their antimicrobial activity. Collected plant materials are dried and the soluble extracts are made using organic solvent like ethanol, methanol and acetone . Antimicrobial activities are measured using agar disc diffusion method. Greater the area of inhibition zone indicates the presence of good potentiality of antimicrobial activity. Antimicrobial activity of three plant parts like frond extracts of Eupatorium odoratum, Artemisia dubia and Bergenia ciliata are tested. Frond extracts of these species show good antimicrobial activity.

Keywords: Antimicrobial, frond, extract, gram(+)ve and gram(-)ve.
