Abstract
The leaves, stem, flowers and fruits of Azadiracta indica .A Juss. which have some
medicinal applications were investigated. Phytochemical analysis gave positive results for steroids,
triterpinoids, reducing sugars, sugars, alkaloids, phenolic compounds, flavonoids and tannins. The crude
methanol extracts showed growth inhibitory effects on Xanthomonas campestris. The methanol extract of
the leaves and fruits showed significant inhibitory effect when compared with positive controls, neomycin
and kanamycin respectively. The stem and flowers extracts show marked antibacterial activity. Among
these samples, the MIC value of leaves and fruits determined by serial dilution technique was found to be
32μg/ml and 64μg/ml against Xanthomonas campestris respectively.
