Evaluation of Sida acuta subspecie acuta leaf/flower combination for antimicrobial activity and phytochemical constituents

Abstract

Sida acuta subspecie acuta Ieaf/flower combination was evaluated for antimicrobial activity and phytochemical constituents using methanol, hexane, chloroform and aqueous method of extractions. The antibacterial activities were exhibited by the four extracts on E. coli, S pyogenes, P.multocida and S. typhumrium as there was no activity exhibited on S. tyhi, S. pneumoniae and K. phneumoniae. Phytochemical analyses revealed the presence of alkaloid, tannin, flavonoid and saponin whereas steroid and glycoside were absent.
