利用水蒸气蒸馏法提取湖南产厚朴叶的挥发油成分,采用GC-MS联用技术结合化学计量学方法（直观推导式演进特征投影法和选择性离子法）进行分析,同时结合程序升温保留指数辅助定性。结果共鉴定出54种化合物,占挥发油总量的84.95%。主要化学成分为α-、β-和γ-桉油醇,含量分别为13.10%、28.21%和14.67%。此外,含量较高的化合物还有α-蒎烯（2.96%）、芳樟醇（1.71%）、丹皮酚（1.88%）、石竹烯（2.04%）、佛术烯（3.60%）、α-瑟林烯（3.84%）和[1AR-（1Aα,4α,4Aβ,7Bα）]-1A,2,3,4,4A,5,6,7B-八氢化-1,1,4,7-四甲基-1H-环丙烯并[E]奥（1.34%）。研究表明,将化学计量学方法用于中药挥发油成分的...

Volatile components of Cortex Magnoliae Officinalis leaves from Hunan were extracted by steam distillation and analyzed by gas chromatography-mass spectrometry combined with chemometrics methods,namely heuristic evolving latent projections and selective ion analysis.Temperature-programmed retention indices were used to improve the reliability of qualitative analysis.Total 54 compounds were identified,accounting for 84.95% of the total content of volatile ingredients of the studied sample.The major constituents are alpha-,beta-and gamma-eudesmol...
