308ANTIMICROBIAL ACTIVITY OF HYDROMETHANOLIC EXTRACT OF CASSIA FISTULA SEEDSIn the present study, the antibacterial activity of methanolic extract of Cassia fistula was tested, which is a deciduous and an ornamental tree native to India and Sri Lanka, (Family – Caesalpinaceae) (Tamil – Sarakondrai). The methanol extract of Cassia fistula seeds was investigated for potential antimicrobial activity against different medically important bacterial strains. Disk diffusion technique was used to determined antimicrobial activity. The extract was effective on tested microorganism. Hence, this plant can be used to discover bioactive natural products that may leads in the development of new pharmaceuticals that address not fulfilled therapeutic needs.kushwahamaya21@gmail.comResearch4112013Cassia fistula,Methanolic extract,Phytochemical,AntimicrobialKushwaha Maya,Banerjee MeenakshiLaboratory of algal Biotechnology, Biosciences Department, Barkatullah University, Bhopal, M.P., India.,Laboratory of algal Biotechnology, Biosciences Department, Barkatullah University, Bhopal, M.P., India.
