The antimicrobial activities of the extracts are reported against Escherichia coli ATCC 29998, Escherichia coli ATCC 25922, Staphylococcus aureus ATCC 6538P, Staphylococcus epidermidis ATCC 12228, Salmonella thy-phimurium CCM 5445, Enterobacter cloacae ATCC 13047 and Enterococcus faecalis ATCC 29212 as bacteria and Candida albicans ATCC 10239 as yeast by using the disc diffusion method. It is observed that ethanol extract showed activity against Gram (+) and Gram (-) bacteria. None of the tested extracts showed antifungal activity against Candida albicans ATCC 10239.
