BIOAUTOGRAPHY SCREENING OF A MANGROVE Excoecaria agallocha L. 

 

ABSTRACT

                The aqueous leaf extracts of Excoecaria agallocha were evaluated for antibacterial activity along with their phytochemical screening. The minimum inhibitory concentration (MIC) of gram positive and gram negative organisms were analysed by micro titre plate technique. Preliminary phytochemical screening revealed the presence of tannins, alkaloids, steroids, flavonoids and anthroquinone glycosides which might be the responsible factors for bioactivity against chosen bacterial pathogens. Hence Excoecaria agallocha aqueous leaf extracts is more sensitive for gram negative organisms.

 

Key words: Excoecaria agallocha, Antibacterial activity, MIC, Phytochemical screening.
