CHEMICAL COMPOSITION AND ANTIFUNGAL ACTIVITY OF ESSENTIAL OILS FROM AERIAL PARTS OF MENTHA PIPERITA AND MENTHA ARVENSISAbstract
The present study deals with chemistry and antifungal activity of essential oil (EO) of two species of Mentha viz. Mentha piperita and Mentha arvensis which was extracted using Clevenger-type apparatus. Percent yield of EO of M. arvensis (2.8%) was found higher than M. piperita (2.1%). Compositional analysis of M. piperita and M. arvensis EO oil by GC-MS revealed presence of 51 and 35 compounds, respectively. Vibration spectroscopy performed in the 500-4000 cm-1 wave number region depicted variations in the presence of functional groups among the two EOs. The M. piperita EO exhibited better antifungal potential against Penicillium digitatumin comparison to M. arvensis EO. The results were found at par with the standard Carbendazim 50 WP at 250 µg/mL. Optical research microscopy study depicted profound morphological changes in hyphae and spore bearing organs of EO treated fungus thereby supporting better antifungal activity of M. piperita EO.
