Abstract

Extracts of powdered leaf and bark, of an endangered plant Lasiosiphon eriocephalus Decne (Family: Thymelaeaceae), taken in different solvents (viz. Petroleum ether, Methanol and Chloroform) was tested for antimicrobial activity against pathogens- Escherichia coli, Staphylococcus aureus, Klebsiella sps. and Xanthomonas oryzae. It was found that methanol extract of both leaf and bark containing Coumarins, had higher antimicrobial capacity than chloroform extract. Petroleum ether extract of neither leaf nor bark showed any antimicrobial activity. Presence of Coumarins in the methanolic extracts of leaf and bark was detected using HPTLC analysis. For all the extracts, 5 mg/ml was found to be the optimal concentration for exhibiting antimicrobial activity against all the tested microbes. Key words: Lasiosiphon eriocephalus, Antimicrobial activity, HPTLC analysis, Endangered plant.
