Biochemical analysis and Antibacterial effect of Cymbopogan citratus against selected pathogens

Dave Jyoti

Abstract :

 The present study is based on the biochemical analysis and investigation of antibacterial activity of aqueous and ethanolic extracts of Cymbopogan citratus. The microorganisms used in the study are pathogens viz Staphylococcus aureus, Proteus vulgaris and Escherichia coli. The susceptibility of bacterial strains against the two extracts was determined using disk diffusion method. The most susceptible microorganism was S. aureus while the least susceptible organisms were E.coli. Highest antibacterial activity was observed with ethanolic extract of Cymbopogan citratus against S.aureus (12mm) while minimum activity was observed with aqueous extract against E.coli (5mm). Ethanolic extract of the sample is more effective in comparison to the aqueous extracts in inhibiting the growth of pathogens under study. They were less potent when compared with ciprofloxacin used as positive control. Biochemical analysis shows the presence of alkaloid, flavanoids, and tannins in both the extracts of Cymbopogan citrates while steroids were found only in the aqueous extracts of the plant.
