ABSTRACT
A fruticose lichen Ramalina hossei from Darjeeling Hills was screened for its antimicrobial activity against eight microorganisms. The ethanolic and methanolic extracts of R. hossei exhibited antimicrobial property against Gram positive bacteria, Gram negative bacteria and a fungus. Identification of active principle in lichen extract and the probable active compounds were identified by LCMS analysis. LCMS Chromatogram of methanolic extract of Ramalina hossei 7904 (SAIF) indicated the presence of occurrence of different group of phytochemicals which may be explored for the development of widely acceptable agents to combat disorders without any side effects.
