Aromatic and medicinal plants are widespread and Kashmir valley possesses their rich repository. The agro climatic conditions prevailing in this region provide an ideal habitat for the natural growth of variety of plant species which are of prime importance in pharmaceutical, food and cosmetic industries. The present study was conducted to analyse the essential oil obtained from Origanum vulgare (L.) family Lamiaceae and the variability in oil composition of the same species growing at different geographical locales. Essential oils obtained from aerial parts of three Origanum vulgare L. samples, growing wild in different locations viz. Srinagar, Pulwama and Yaarikhah regions of Kashmir were obtained by hydro-distillation of the aerial parts and analysed by Gas Chromatography coupled with Mass Spectrometry (GC-MS) for their chemical composition. Overall sixteen to thirty four numbers of constituents were isolated and identified in its oil. The major compounds were gamma terpinene, para cymene, carvacrol, cymene, sabinene and cis sabinene hydrate acetate. Three chemotypes were found: the first growing at Srinagar locale with a prevalence of γ-terpinene/ cymene / sabinene; the second growing at Pulwama characterised with a prevalence of γ-terpinene/p- cymene / sabinene /carvacrol and the third growing at Tangmarg featuring a prevalence of p-cymene / carvacrol /cis-sabinene hydrate acetate /γ-terpinene. The results of essential oil analysis show rich composition of oil compounds. Moreover, the percentage composition of the main components of its essential oil showed marked differences as a result of changing geographical regions. One can expect that the germplasm of O. vulgare is a potentially important source of genetic variation.
