The present study aimed at assessing the antibacterial activity of two varieties of garlic
(ophioscordon and sativum) against enteric pathogens such as Escherichia coli, Proteus mirabilis, Salmonella typhi, Shigella flexineri and Enterobacter aerogenes. Aqueous extract of both the garlic varieties inhibited the
growth of enteric pathogens at the concentrations of 200,300,400 and 500mg. However Enterobacter
aerogenes was not susceptible to the aqueous extract of both the garlic varieties. Ethanolic extract of sativum
was found to be highly effective against all the bacteria tested. HPTLC analyses of garlic varieties confirm the
presence of allicin in various concentrations. Further analysis using GC-MS identified other compounds such
as n-hexadecanoic acid, 3-deoxy-d-mannoic lactone, thym ine and hexanedioic, bis (2-ethylhexyl) ester.
Key words: Antibacterial activity, HPTLC, GC-MS, allicin, palmitic acid, ,
