Evaluation of Anti Microbial Activity of Cynodon dactylon

To investigate the antimicrobial activity of Ethanol, Methanol, Acetone, Chloroform, Hexaneand Petroleum ether extract of Cynodon dactylon (L.) Pers.(Family - Poaceae) was tested againstinfectious disease causing bacterial pathogens such as such as E.Coli, Pseudomonas aeruginosa,Staphylococcus aureus and Klebsiella pneumonia fungus like Aspergillus niger, Candidaalbicans, Candida kefyr and Candida tropicalis using the Agar Well diffusion method. It was observed that Ethanol, Methanol, Acetone, Chloroform, Hexane and Petroleum ether showed activity against Bacteria and Fungi. The Ethanol extract of Cynodon dactylon showed more activity against Pseudomonas aeruginosa zone of diameter 13.83±0.29 and Staphylococcus aureus zone of diameter 12.0±0.10 and the Ethanol extract of Cynodon dactylon showed more activity against Aspergillus niger zone of diameter 12.23±0.21 and Candida albicans of diameter 11.0±0.20, when compared to other solvent extracts . In the present study, both in bacteria and fungi ethanol extract showed a varying degree of inhibition to the growth of tested organism than Methanol, Acetone, Chloroform, Hexane and Petroleum ether. The results confirmed that presence of antibacterial and antifungal activity in the sundried extract of Cynodon dactylon against the human pathogenic organisms.KEYWORDS: Cynodon dactylon, Pseudomonas aeruginosa, Staphylococcus aureus,Aspergillus niger, Candida albicans.
