Abstract

The aim of present study is to investigate the phytochemical constituents and antimicrobial activity of Ethanolic extract of Sonneratia apetala. Preliminary Phytochemical tests revealed the presence of alkaloids, flavonoids, tannins , saponins , phytosterols and carbohydrates. Antimicrobial activity was evaluated by Agar well Diffusion method. In vitro screening of Sonneratia apetala mangrove Ethanolic plant extract showed species specific activity in inhibiting growth of bacteria and fungi. The Ethanolic plant extract showed good activity against sel ected gram - positive bacteria ( Bacillus subtilis, Staphylococcus aureus, Staphylococcus w e rneri ), g ram - negative bacteria ( Pseudomonas putida, Escherichia coli, Pseudomonas ae ru ginosa, Proteus mirabilis , Klebsiella pneumonia) and fungal strain ( Candida albic ans). The observations revealed significant zone of inhibition and supports to antimicrobial activity. The bioactive compounds responsible for these antimicrobial activities could be isolated and identified to develop a new drug of pharmaceutical inter est.
