Abstract

Chemical composition and antimicrobial effects of ESSENTIAL OILS of THYMUS X-PORLOCK and MENTHA LONGIFOLIA were studied. Disc diffusion method was conducted to evaluate the zone of E. coli and S. AUREUS growth inhibition at various concentrations of the ESSENTIAL OILS. The antimicrobial effect was also studied against three different concentrations of microbial suspension to find out MIC (Minimal Inhibitory Concentration) and MBC (Minimal Bactericidal Concentration). The ESSENTIAL OILS from THYMUS X-PORLOCK and MENTHA LONGIFOLIA were bactericidal against both the micro organisms. Gram negative bacterium, E.COLI, was readily affected as compared to S. AUREUS. Chemical composition of the ESSENTIAL OILS were analyzed by Gas Chromatography and Mass Spectrometry (GC and GC/MS). Five common monoterpene compounds at various concentrations were found in both the oils Viz; α-pinene Limonene, Linalol, Sabinene and Myrcene. α-pinene and Limonene seem to have exerted antimicrobial effect in both the plant extracts. Presence of α-pinene seem to enhance the antimicrobial effect of THYMUS X-PORLOCK.The major compounds found in the ESSENTIAL OILS of THYMUS X-PORLOCK were 1,8-Cineole (54.52%), Sabinene hydrate (5.03%) and thymol (7.89%) and those of MENTHA LONGIFOLIA were Piepritone (43.96%) and Trans-Piperitol (12.5%). Limone of MENTHA LONGIFOLIA was at the highest level of 13.73 percent among monoterpene compounds. The study shows greater bactericidal effect of THYMUS X-PORLOCK ESSENTIAL OILS. With a view to the increasing limitations of the use of chemical antimicrobial agents and development of drug resistance, it seems necessary to switch onto a new harmless antimicrobial agents from natural sources.
