ABSTRACT: Essential
oils obtained from hydrodistillation of three medicinal plants grown in Vietnam
were analyzed by gas
chromatography (GC) and gas chromatography/mass spectrometry (GC-MS). The
monoterpene hydrocarbons, α-pinene
(50.2%), β-pinene (23.6%) and
limonene (5.3%) were the most abundant
constituents of the rhizome oil of Zingiber
collinsii Mood & Theilade (Zingiberaceae). The main compounds of the
stem oil of Croton kongensis Gagnep.,
(Euphorbiaceae) were benzyl benzoate
(12.7%), β-selinene (9.8%), bulnesol
(8.0%) and 5,6,7,8-tetrahydroquinoxaline (7.4%). The leaf oil of Goniothalamus albiflous Ban., consisted
mainly of α-pinene (26.2%), caryophyllene
oxide (10.6%) and 1,8-cineole (9.7%). The composition of the oils of Zingiber collinsii and Croton kongensis was being reported for the first time.
