ANTIBACTERIAL ACTIVITIES OF TRIGONELLA FOENUM-GRAECUM AND ZINGIBER OFFICINALEAbstract
An in vitro study was conducted for screening antibacterial activities of seeds of Trigonella foenum-graecum (fenugreek)and rhizomes of Zingiber officinale (ginger), in their different forms viz. aqueous extracts, essential oils and powders against some common food borne pathogens. Bacterial strains involved in the study were Bacillus cereus (MTCC 430), Enterococcus feacalis (MTCC 439), Escherichia coli (MTCC 1687), Psuedomonas aeruginosa (MTCC 424) and Staphylococcus aureus (MTCC 5021). Results revealed that powdered forms of T. foenum-graecum and Z. officinale remained ineffective in arresting the growth of all the bacterial strains under investigation. During preliminary screening, aqueous extracts and essential oils of test spices did not exhibit any growth inhibitory zone towards any test bacteria. In broth dilution technique, essential oil of Z. officinale arrested all the bacterial strains under observation while essential oil of T. foenum-graecum and aqueous extracts of T. foenum-graecum and Z. officinale remained ineffective.
