Phytochemical and antimicrobial studies on stem bark extract of Sterculia setigera, Del

Abstract

Antibacterial activity using broth and disc diffusion methods, and phytochemical screening was carried out on crude stem bark extracts of Sterculia setigera, a plant used ethnomedically by various communities in Nigeria. These extracts showed low antibacterial activity against Staphylococcus aureus, Proteus mirabilis and Klebsiella pneumonia. Phytochemical screening revealed the presence of alkaloids, phenolics/tannins in acetone and methanol extracts, and triterpenoid in boiling petroleum ether extract. © 2011 Academic Journals.
