Abstract :

Onions (Allium cepa) is a important plant used in diet and in siddha medicines. Allium species are used in traditional medicine for centuries. The present study aimed at assessing the antibacterial activity of onion against three MRS species. Various solvent extracts of onion inhibited the growth of MRS species at the concentrations of 200,300,400 and 500&mu;g. Chloroform extract and petroleum ether extract of Allium cepa (O1) was found to be highly effective against MRS1sp. Methanol and petroleum ether extract of O2 showed good activity against MRS3 species. Chloroform extract of O3 was found best towards MRS 3 species. The extract showed concentration dependent antibacterial activity against methicillin resistant Staphylococcus species (MRSA). The traditional use of onion for infectious diseases and for controlling MRS species infection appears to be justified.
