Alcoholic extract of ginger (Zingiber officinale) and extracts of African oil bean seed (Pentaclethra macrophylla) in six different solvents, viz. petroleum-ether, benzene, acetone, chloroform, ethanol and water were investigated for antibacterial activity. The alcoholic extract of ginger and petroleum-ether extract of oil bean seed showed significant activity against Escherichia coil, Proteus vulgaris, Salmonella typhimurium, Staphylococcus aureus and Streptococcus viridans. The antibacterial activity of benzene, acetone and chloroform extracts of oil bean seed was less marked while its alcoholic and aqueous extracts showed no activity. Some of the oil bean seed extracts showed slight activity for Streptococcus faecalis while none of the extracts exhibited any action against Pseudomonas aeruginosa.
