S. Gupta, G. Bhaskar and H.C. Andola

Abstract

In the present investigation two essential oil components linalool and limonene quantity were estimated in the leaves of male and female plants of different altitudes (775, 1100 and 1650 m). The plant material collected from different sites was named as Z-1, Z-2 and Z-3, respectively. The essential oil obtained was dark greenish black in bulk, yellowish green in thin layers, very fluid and had an odor of ether. In Z-1, Z-2 and Z-3 female leaves linalool was found to be 34.1, 27.2 and 11.7% and limonene to be 1.6, 2.4 and 6.4%, respectively. In male leaves also significant variation was found in the quantity of linalool and limonene in plants of different altitudes. In Z-1, Z-2 and Z-3 male leaves linalool was found to be 35.6, 19.8 and 10.0% and limonene to be 2.8, 4.0 and 4.5%, respectively.
