Abstract

Traditional medicine particularly herbal medicine considered as a major healthcare provider around the globe, particularly in rural and remote areas. Herbal medicines are gaining much importance nowadays as it is cheap, easily available and have lesser side effects. The current investigation deals with efficacy of methanolic leaf extracts by carrying out the phytochemical screening and qualitative analysis as well as to check their efficacy against selected antibiotic susceptible and resistant microorganisms. Phytochemicals obtained from selected leaf extract of seven taxa were alkaloids, tannins, flavonoids, saponins, steroids and phenol which were traditionally used to treat cough, low B.P, respiratory infections and gonorrhea. Over and above, the results confirmed the ethnomedicinal uses of four plant taxa by showing the inhibitory action against microorganisms; among which the most significant one is Polyalthia longifolia, against Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, Salmonella typhi and Serratia marcescens.
