Abstract

Abstract: The chemical constituents of essential oils hydrodistilled from the leaves of Uvaria grandiflora Roxb. ex Hornem. and Uvaria microcarpa Champ. ex Benth. grown in Vietnam were identified by the techniques of gas chromatography-flame ionisation detector (GC-FID) and gas chromatography-mass spectrometry (GC-MS). A total of 29 and 13 compounds, representing 96.5 % and 99.9 % of the total oil contents were identified respectively in U. grandifolia and U. microcarpa . The main classes of compounds identified in U. grandiflora were monoterpene hydrocarbons (43.3 %), oxygenated monoterpenes (13.6 %), sesquiterpene hydrocarbons (13.7 %) and benezenoid compounds (17.3 %). However, phenylpropanids (50.8 %) and benzenoid compounds were the main classes of compounds present in U. microcarpa . The main compounds identified in U. grandiflora were limonene (25.2 %), benzyl benzoate (16.0 %), α-phellandrene (10.2 %), eugenol (7.3 %) and 1, 8-cineole (6.1 %). However, eugenol (50.8 %) and benzyl benzoate (34.8 %) were the two major compounds identified in the leaf oil of U. microcarpa.
