Abstract

Antibacterial activity of twelve crude alcoholic and aqueous extracts from six medicinal plants against Staphylococcus aureus ATCC 25923 and Escherichia coli ATCC 25922 was studied. The medicinal plants included Alstonia macrophylla Wall., Bixa orellana L., Blumea balsamifera (L.) D.C., Azadirachta indica A. Juss., Arcangelisia flava (L.) Merr., and Leea rubra Blume. Crude ethanolic extracts from leaves of Bixa orellana L. and bark of Alstonia macrophylla Wall. showed potential antibacterial effect against S. aureus with minimal inhibitory concentration (MIC) of 62.5 μg/ml. However, none of the crude aqueous and ethanolic extracts showed antibacterial effect against E. coli.
