Rhizome and Leaf Oil Composition of<i>Curcuma longa</i>from the Lower Himalayan Region of Northern India

Abstract

Abstract The essential oils of Curcuma longa L. (Zingiberaceae) were isolated from its rhizomes and leaves by hydrodistillation. The oils were analyzed by high resolution GC and GC/MS. Fifty-two constituents were identifed from rhizome oil representing 98.6% of the oil. The major constituents of the oil were α-turmerone (44.1%), β-turmerone (18.5%) and ar-turmerone (5.4%). From the leaf oil, 61 compounds were identifed constituting 99.8% of the oil and main constituents were α-phellandrene (53.4%), terpinolene (11.5%) and 1,8-cineole (10.5%).
