Title: Antibacterial Activity of<i>Origanum vulgare</i>L. Populations of Indian origin
Abstract: Abstract Origanum vulgare L. (Lamiaceae) is a popular spice and medicinal plant, widely distributed in Himalayan region of India. In present study, the essential oils of two O. vulgare populations have been evaluated for their antibacterial potential. Chemical composition of the hydrodistilled essential oils was ascertained by GC-FID and GC-MS techniques. Major components of the population ‘I’ were thymol (40.4 %), p-cymene (12.3 %), γ-terpinene (10.5 %), carvacrol (9.9 %), and carvacrol methyl ether (4.4 %), whereas the population ‘II’ was dominated by carvacrol (64.6 %), p-cymene (13.9 %) and γ-terpinene (12.0 %). Antibacterial activity of the essential oils was evaluated against six pathogenic bacterial strains, viz. Staphylococcus aureus, Staphylococcus epidermidis, Enterococcus faecalis, Streptococcus mutans, Enterobacter aerogenes, and Kleibsiella pneumoniae. Both oils exhibited strong antibacterial activity with the minimum inhibitory concentration (MIC) ranging from 1/1600 to 1/6400.
