• Dasymaschalon longiusculum
• Dasymaschalon glaucum
• Dasymaschalon robinsonii
• alpha-pinene
• beta-pinene
• bicycloelemene
• alpha-copaene

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 (Ban) yielded oils in which the major components were -pinene (28.9% and 12.5%, respectively), -pinene (26.5% and 13.3%, respectively), -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 -pinene (14.4% and 10.5%, respectively), -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 -copaene (12.7% and 16.6%, respectively), germacrene B (11.3% and 7.5%, respectively), -cadinene (5.6% and 5.3%, respectively) for the leaf and stem.
