作者用气-质联用的方法分析了异叶败酱(Patrinia heterophylla)根与根茎的挥发油化学成分。鉴定出α-蒎烯、β-蒎烯、柠檬烯、δ-榄香烯、龙脑、α-松油醇、β-马阿里烯、β-愈创烯、δ-荜澄茄烯和γ-榄香烯等10种成分。其中的β-蒎烯、α-松油醇和δ-榄香烯等成分的含量较高,用气相色谱法分离得到,并进行了IR光谱鉴定。 The authors analyzed the chemical constituents of volatile oil from the roots and rhizomes of Patrynia heterophylla by gas chromatography-mass spectrometry. Α-pinene, β-pinene, limonene, δ-elemene, borneol, α-terpineol, β-maarilin, β-guaiacene, δ-cuminoleone, and γ- were identified Elemene and other 10 ingredients. The contents of β-pinene, α-terpineol and δ-elemene were high, and they were separated by gas chromatography and identified by IR spectroscopy.
