Abstract This study was aimed to investigate the chemical compositions of the essential oils from Goniothalamus macrophyllus and Goniothalamus malayanus growing in Malaysia. The essential oils were obtained by hydrodistillation and fully characterized by gas chromatography (GC–FID) and gas chromatography–mass spectrometry (GC–MS). Analyses of the essential oils from G. macrophyllus and G. malayanus resulted in 93.6 and 95.4% of the total oils, respectively. The major components of G. macrophyllus oil were germacrene D (25.1%), bicyclogermacrene (11.6%), α-copaene (6.9%) and δ-cadinene (6.4%), whereas in G. malayanus oil bicyclogermacrene (43.9%), germacrene D (21.1%) and β-elemene (8.4%) were the most abundant components.

Goniothalamus macrophyllus 和 Goniothalamus malayanus 叶精油的化学表征

摘要 本研究旨在研究生长于马来西亚的大叶角藻和马来角藻精油的化学成分。精油通过水蒸馏获得，并通过气相色谱 (GC-FID) 和气相色谱-质谱 (GC-MS) 进行充分表征。G. macrophyllus 和 G. malayanus 的精油分析结果分别占总油的 93.6% 和 95.4%。G. macrophyllus oil 的主要成分是germacrene D (25.1%), bicyclogermacrene (11.6%), α-copaene (6.9%) and δ-cadinene (6.4%), 而G. malayanus oil bicyclogermacrene (43.9%),锗烯 D (21.1%) 和 β-榄香烯 (8.4%) 是最丰富的成分。
