Abstract
The study was carried out to assess antibacterial bioassay of Withania Somnifera. The antimicrobial activities of the butanol, n-hexane, chloroform, ethyl acetate and aqueous extracts of With ania Somnifera. were investigated. The bacterial strains used were E.coli, C.albican, B. atropeous, Pseudomonas aeruginosa, Klebsiella pneumonia, Staphylococcus Aureus and Salmonella, that highest zone of inhibition 14 mm resulted for the ethyl acetate extract of With ania Somnifera against I! aeruginosa and Chlorform extract against E. coli. Other significant results obtained by different crude extracts are 13 mm, 12mm and 11 mm against E. coli, C. albican, B. atropeous, Pseudomonas aeruginosa, Klebsiella pneumonia, Staphylococcus Aureus and Salmonella. Aqueous, n-hexane and chloroform extract were found totally inactive against Salamonella
