Investigation of Broad-Spectrum Antimicrobial Potential in Selected Ethnomedicinal Plant Extracts

Abstract

In the present investigation the antimicrobial activity of Emblica officinalis Gaertn, Syzgium aromaticum (L.) Merr. & L.M.Perry, Eucalyptus globulus Labill., Solanum tuberosum L, Pyrus communis L, Prunus armeniaca L. were evaluated. The plant material was extracted through maceration method in different polar and non-polar solvents that are petroleum ether, chloroform, methanol, Distill water having different concentrations of 30%,50%,70% and 100% and the results were noted against Candida albicans (C.P.Robin) Berkhou and Staphylococcus aureus Rosenbach. Well diffusion method is used for this purpose. The zones of inhibitions were measured against these strains and result were compared with commercially available standard antimicrobial discs. The standard discs used in the experiment were Flucanozole and Clindomycin. Chloroform extraction (30 %) Emblica officinalis showed the maximum inhibitory zone of 16.5±0.5 in 30% concentration of chloroform and in the same way Prunus armeniaca showed minimum inhibitory zone of 10.5±0.7 in 30% concentration of methanol against Candida albicans. Syzgium aromaticum showed highest inhibitory zone of 25.16±0.76 in 30% concentration of chloroform while Solanum tuberosum showed lowest inhibitory zone of 10.1±0.7 in 100% concentration of chloroform against Staphylococcus aureus
