Preliminary Phytochemical Screening and Antimicrobial Activity of Methanol Extract of Crotalaria Burhia

Methanol, chloroform, petroleum ether and aqueous extract of Crotalaria burhia (whole plant) were investigated for their antibacterial activity against Staphylococcus aureus using cup plate agar diffusion method. The 4 extracts tested, the methanol extract presented the best results. Various investigations like physicochemical standards, preliminary phytochemical screening of the plant was carried out, and the salient qualitative parameters were reported. The present paper deals with the investigation of various photochemical present in various extract and in vitro antibacterial activity. It is concluded that the plant studied may be a source of antibacterial agent.
