Abstract

The hydro-distillation essential oil was obtained from the leaf, stem, and flower of Blumea paniculata (Willd.) M.R.Almeida (Asteraceae) and analysed using gas chromatography equipped with a flame ionisation detector (GC-FID) and gas chromatography coupled with mass spectrometry (GC-MS). Fifty-eight, sixty-nine and, fifty-seven constituents were identified from leaf oil (LO), stem oil (SO) and flower oil (FO), representing 95.8%, 96.3% and 95.1% of the total oil constituents, respectively. The major constituents were identified as germacrene D (39.6–48.1%), α-humulene (4.9–8.9%), β-caryophyllene (4.8–7.7%), and α-cadinol (2.9–6.8%) from different parts of the plant B. paniculata. The oils were found to be rich in sesquiterpenoid-type constituents.

摘要

水蒸馏精油取自Blumea paniculata (Willd.) MRAlmeida（菊科）的叶、茎和花，并使用配备火焰离子化检测器 (GC-FID) 的气相色谱法和气相色谱联用质谱法进行分析(GC-MS)。从叶油 (LO)、茎油 (SO) 和花油 (FO) 中鉴定出 58、69 和 57 种成分，分别占总油成分的 95.8%、96.3% 和 95.1% . 主要成分被鉴定为 germacrene D (39.6–48.1%)、α-葎草烯 (4.9–8.9%)、β-石竹烯 (4.8–7.7 %) 和α -cadinol (2.9–6.8%) 来自不同部位植物B. paniculata. 发现这些油富含倍半萜类成分。
