Abstract
Phytochemical screening and antibacterial activity of aqueous extracts of bark and leaf of eighteen mango varieties growing in the village Hanavadi, Malavalli taluk, Mandya district, Karnataka state were conducted. They showed the presence of alkaloids, steroids, flavonoids, tannins, cardiac glycosides, saponnins, resins, carbohydrates and proteins. Antibacterial activity tested against six human pathogens- Escherichia coli, Enterobacter aerogenes, Staphylococcus aureus, Streptococcus mutans, Pseudomonas aeruginosa and Bacillus subtilis, by disc diffusion method showed significant inhibition zone against pathogens compared to control. These results disclose the inhibiting property of leaf and bark of wild varieties of mangoes against potential pathogens and thus can be subjected to further investigations for their applications in human phytomedicines.
