Analysis of essential oil constituents of three Dasymaschalon species (Annonaceae) from Vietnam.
The compositions of essential oils of the leaves and stem barks of three Vietnamese species of Dasymaschalon J. D. Hooker & Thomson. (Annonaceae) were determined by means of gas chromatography and gas chromatography-mass spectrometry. Dasymaschalon longiusculum (Bân) yielded oils in which the major components were α-pinene (28.9% and 12.5%, respectively), β-pinene (26.5% and 13.3%, respectively), β-myrcene (12.0% and 6.0%, respectively) for the leaf and stem. The main compounds of the leaf and stem oils of Dasymaschalon glaucum Merr. & Chun. were α-pinene (14.4% and 10.5%, respectively), β-pinene (14.4% and 10.3%, respectively) and bicycloelemene (5.2% and 30.0%, respectively). The essential oil of Dasymaschalon robinsonii Jovet-Ast was different, mainly comprising α-copaene (12.7% and 16.6%, respectively), germacrene B (11.3% and 7.5%, respectively), δ-cadinene (5.6% and 5.3%, respectively) for the leaf and stem.
