39STUDY OF ACTIVITY OF SOME ETHNOMEDICINAL FERNS OF DARJEELINGThe present aim is to study of some ethnomedicinal ferns having antimicrobial activity and commonly found around the area of district Darjeeling of West Bengal, India. Common ethnomedicinal ferns from several areas of Darjeeling district 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. Antimicrobial activities are measured using agar cup diffusion method. Greater the area of inhibition zone indicates the presence of good potentiality of antimicrobial activity. Antimicrobial activity of three plant parts like rhizome, rachis and frond extracts of Adiantum capilusveneris Linn, Nephrolepis cordifolia Linn and Pteris vitata Linn is tested. Frond extracts of these species show good antimicrobial activitySamirpal1957@gmail.comResearch412014Antimicrobial,Rachis,Rhizome,Frond,ExtractSamir Kumar PalP.G.
