The organic extracts of Withania somnifera, Gymnema sylvestre and Cannabis sativa have been evaluated of antimicrobial activity against P. aeruginosa, E. coli and C. albicans. The antimicrobial activity of ethanolic extracts (20 mg/mL) of W. Somnifera was (44, 45, 42 mm) against P. aerouginos, E. coli and C. albicans, respectively. The antimicrobial activity of G. sylvestre petroleum ether extract was 20 mm against P. aeruginosa. The antimicrobial activity of Gymnema sylvestre water: ethanol extract was 18 mm against E. Coli. The antimicrobial activity of G. sylvestre chloroform extract was 20 mm against C. albicans. The antimicrobial activity of G. sylvestre chlorofomic extract (10 mg/mL) was 21, 27 and 19 mm against P. aerouginosa, E. coli and C. albicans respectively. The Cannabis sativa antimicrobial activity of extracts (hexane and propanol) was 20 and 23 mm against P. aerugenosa and C. albicans, respectively. The antimicrobial activity of propanolic extracts (10 mg/mL) of C. sativa was 19, 17 and 21 mm against P. aerugenosa, E. coli and C. albicans, respectively.
