Abstract

The leaves of Crotalaria lachnosema were freshly collected, dried under-shade and ground into powder. The ethanolic extract of the sample was obtained by cold extraction and was fractionated with solvent of varied polarity. The fractions were analyzed for their phytochemicals and screened antimicrobial against Staphylococcus aureus, Salmonella typhi and Escherichia coli. The phytochemicals were distributed among the test fractions. Tannins were found to be present in all the fractions and methanol fraction contains all the other tested phytochemicals except alkaloids and cardiac glucosides. The activities of the fractions were found to be more pronounced against E. coli than against the other test organisms.
