采用水蒸气蒸馏法提取小飞蓬新鲜叶子中的挥发油,采用气相色谱-质谱联用技术(GC-MS)和峰面积归一化法分离分析其化学成分和相对含量。结果表明,小飞蓬新鲜叶子挥发油得率为0.74%,共可分离30种化合物,鉴定出其中的26种,占挥发性成分总量的96.12%。挥发油的主要成分有金合欢烯(18.13%)、β-毕澄茄烯(15.02%)、橙花叔醇(12.04%)、环己醇(9.28%)和榄香烯(8.46%)。
Volatile oil was extracted from fresh leaves of Radix phoebe by steam distillation. The chemical constituents and relative contents were separated and analyzed by gas chromatography-mass spectrometry (GC-MS) and peak area normalization. The results showed that the volatile oil yield of fresh leaves was 0.74%. A total of 30 compounds were isolated and 26 of them were identified, accounting for 96.12% of the total volatile components. The main constituents of volatile oil are farnesene (18.13%), β-beegone (15.02%), nerolidol (12.04%), cyclohexanol (9.28%) and elemene (8.46%).
