EVALUATION OF ANTIBACTERIAL ACTIVITY OF VOLATILE OIL FROM MENTHA SPICATA L.
Volatile oil from the herbs of Mentha spicata L. (family Lamiaceae) were extracted from ten different natural habitats of Uttarakhand and their antibacterial potential was analyzed. Leaves oil were extracted by hydro distillation using Clavengerâ€™s apparatus. The oil yield varied from 0.57%-1.4%. The essential oil rich in carvone and piperitone oxide were exploited for determining antibacterial potentials by disc diffusion assay. These oils showed antibacterial activities against three gram negative (Salmonella enterica enterica, Escherichia Coli and Pasturella multocida) and one gram positive (Staphyllococcus aureus) bacteria with varying magnitudes. Volatile nature of plant essential oils can be explored drugs for prevention and treatment of pathogenic diseases.
