Antibacterial activity of Alstonia scholaris and Leea tetramera.
The crude methanolic extracts of the leaves, stem and root barks of Alstonia scholaris and Leea tetramera on partitioning (petrol, dichloromethane, ethyl acetate, butanol) gave fractions exhibiting improved and broader spectrum of antibacterial activity. Especially the butanol fractions of A. scholaris and the root bark of L. tetramera. None of the fractions were active against the fungi tested.
