Variation in the Composition of the Essential Oils of Rosmarinus officinalis L. Grown in Sub-Tropical Region of Jammu and Temperate Region of Kashmir, India

Abstract

A comparison of constituents of Rosmarinus officinalis L. oils, grown in two different climatic regions of Jammu & Kashmir, has been carried out by gas chromatography-mass spectrometry to perform separation and identification of the constituents of the essential oil. The comparative study has resulted in establishing a chromatographic technique for authenticating the variations in chemical composition with change in climatic conditions. Substantial variations in the constituents of essential oil were observed. The technique has also helped in identifying a different Eco-type of rosemary.
