Abstract:
Neem Leaves (Azadirachta indica A. Juss) collected in Binh Thuan province in May have been shown to contain alkaloids (0.66%), flavonoids (2.95), coumarins, reduced sugars and lipids. The alkaloid fraction gave 6 spots and the flavonoid fraction yielded 7 spots on this layer chromatography. Two substances, i.e., A6, an alkaloid and a flavonoid suspected to be Azadirachin A, have been isolated for further study. Liquid extract of Neem Leaves exerted anti-microbial activity against Staphylococcus aureus, Escherichia coli, Salmonella typhi, Pseudomonas aeruginosa and candida albicans
