Antibacterial activity and phytochemical content of Avicennia Marina collected from polluted and unpolluted site

M Ananthavalli and S Karpagam

The aim of the present study is to evaluate the phytochemical content and antibacterial activity of Avicennia marina collected from polluted and unpolluted site from the back-waters of Attipatuputhunagar. The plants were collected separately and tested for phytochemical analysis and antibacterial activity against various bacteria such as Salmonella typhi, Staphylococcus aureus, Escherichia coli and Klebsiella pneumonia. Preliminary phytochemical analysis was performed with ethanol and aqueous extract of Avicennia marina plant leaf collected from polluted and unpolluted sites that showed the presence of alkaloids, phenols, tannin, flavonoids, aminoacids, diterpenes, oxalate, cardiac glycosides, quinone, anthocyanin, leucoanthocyanin and Xanthoprotein. The ethanol extract showed the presence of higher phytochemical content when compared to the aqueous extract. The plant collected from polluted site showed the presence of only less amount of phytochemical content when compared to unpolluted site. The ethanol extract of the leaf exhibited significant antibacterial property against tested bacterial organisms. The activity of the extract was comparable with the standards amoxicillin. In conclusion, the result of the present study showed the presence of wide spectrum of antibacterial activities against all the above bacterial pathogens studied. The maximum zone of inhibition was observed in ethanol extract when compared to aqueous extract of unpolluted site plant leaf.
