CHEMICAL CHARACTERIZATION OF ESSENTIAL OIL FROM THE RHIZOMES OF KAEMPFERIA ROTUNDA L. BY GC/MS TECHNIQUE

Abstract

The essence oil from the fresh rhizomes of Kaempferia rotunda L. was isolated by water distillation and analyzed by gas chromatography-mass spectrometry (GC/MS) method. Fifty seven components were identified in the rhizomes oil, which accounted to 99.74% of the oil. The major components were endo-borneol (9.30%), dehydro iso androsterone acetate (9.12%), naphthalene, decahydro-1,1,4a-trimethyl-6-methylene-5-(3-methylene-4-pentenyl),[4aS-(4aα,5β,8aα)]- (9.03%), and β-phellandrene (7.08%), other prominent constituents were 2-propenoic acid, 3-(3-methoxyphenyl)-, ethyl ester (4.47%), a-pinene (3.39%), ethyl cinnamate, trans (3.15%), 2,6-octadienoic acid, 3,7-dimethyl-, methyl ester (2.90%) and camphene (2.89%).
