Abstract
an (Zingiberaceae) growing in Vietnam was performed by means of gas chromatography-flame ionization detector (GC-FID) and gas chromatography-mass spectrometry (GC-MS) techniques. The yields of essential oils were 0.22%, 0.16% and 0.30% (v/w) respectively for leaf, stem and root, calculated on a dry weight basis. The main constituents of the leaf oil were δ-elemene (17.0%), β-pinene (12.8%) and β-elemene (8.8%). The stem oil comprised mainly of δ-elemene (20.1%), germacrene D (8.6%) and bicyclogermacrene (8.1%). The root oil had an abundance of β-pinene (21.0%), δ-elemene (12.8%) and bornyl acetate (11.8%). This is the first report on the volatile constituents of Z. nitens.
