International Journal of Pharma and Bio Sciences EVALUATION OF ANTIBACTERIAL ACTIVITY OF SOME LICHEN FROM RAVANGLA, SIKKIM, INDIA
نویسندگان
چکیده
Antibacterial activity of acetone, methanol and aqueous extract prepared from some lichen species were evaluated against five bacterial strains viz. Staphylococcus aureus, Escherichia coli, Vibrio cholerae, Shigella dysenteriae. Shigella flexneri The aqueous, methanol and acetone extracts exhibited a variable range of antibacterial activity to bacterial strains. The acetone and methanol extracts of all investigated lichens showed selective antibacterial activity. The methanol extracts were usually the most active against test organisms. An aqueous extracts of investigated lichens were found to be inactive against all tested bacteria.
