Abstract

This paper reports the chemical constituents of essential oils from various parts of Decaspermum parviflorum (Lam.) J. Scott. (Myrtaceae) from Vietnam. The essential oils were obtained by hydrodistillation and analyzed by gas chromatography with flame ionization detection (GC-FID) and gas chromatography coupled to mass spectrometry (GC/MS). The main constituents of the oils were β-elemene (1.68–4.14%), caryophyllene (14.53–43.98%), humulene (3.99–10.74%), eudesma-4(14),(11)-diene (4.83–17.46%), α-selinene (3.65–13.60%), cadina-1(10),4-diene (1.0–3.17%), and seline-3,7(11)-diene (1.13–3.20%). Caryophyllene oxide (2.38–3.63%), ylangene (1.22–3.20%), guaia-3,9-diene(1.46–4.50%), eudesma-4(14)-en-11-ol (2.07–2.24%), neointermedeol (1.39–3.25%), aromadendrene oxide-(2) (1.05–1.65%), and naphthalene,1,2,3,4,4a,5,6,7-octahydro-4a,8-dimethyl-2-(1-methylethenyl)- (0.73–2.47%), which were identified only in the flower and fruit. Ocimene (11.87%) and γ-elemene (37.02%) were identified only in the flower. Copaene (8.27%) was identified only in the leaf. This is the first report of the chemical constituents of essential oils from the leaf, fruit, and flower of D. parviflorum, and these constituents differ from those reported for other Decaspermum oils.This paper reports the chemical constituents of essential oils from various parts of Decaspermum parviflorum (Lam.)
