Chemical constituents of essential oils from the leaves and stem barks of four Vietnamese species of Fissistigma (Annonaceae).

Chemical profiles of essential oils from four Fissistigma species: Fissistigma bracteolatum Chatt., Fissistigma villosissimum Merr., Fissistigma latifolium (Dunal) Merr. and Fissistigma glaucescens (Hance) Merr. were analysed by gas chromatography-flame ionisation detector and gas chromatography-mass spectrometry. Fissistigma essential oils consist mainly of sesquiterpenes (48.7-83.8%), monoterpenes (3.2-30.9%) and fatty acids (0.5-33.4%). Data on the essential oil composition of F. villosissimum, F. latifolium and F. glaucescens are reported for the first time.
