野生茅苍术挥发油成分分析

目的:分析野生茅苍术挥发油的化学成分,测定各成分的含量。方法:水蒸气蒸馏法提取野生茅苍术挥发油,用气相色谱-质谱(GC-MS)联用技术分离各成分并鉴定其结构。结果:从野生茅苍术挥发油中分离出44个成分,鉴定出其中33个,主要成分为β-桉叶油醇、苍术酮、茅术醇和苍术素;用峰面积归一化法计算其含量,分别为18.894%、13.707%、11.053%和6.815%。结论:本研究有助于正确评价栽培茅苍术的品质。

Analysis of the Essential Oil Compositions in Atractylodes Lancea

OBJECTIVE： To analyze the chemical compositions of the essential oil from the rhizomes of Atractylodes lancea and determine their relative contents.METHODS： The essential oil was extracted from the rhizomes of Atractylodes lancea by steam distillation method. GC - MS multiple techniques were applied to isolate the constituents and identify their structures. RESULTS： 44 constituents were isolated and 33 of them were detected. The main compositions in the essential oil were β-eudesmol, Atractylon, Hinesol and Atractylodin.Computed by area normalization method, the contents of the four compositions were 18.894%, 13. 707%, 11.053% and 6. 815%, respectively.CONCLUSION ： This experiment is conducive to the correct evaluation of the quality of the cultivated Atractylodes Lancea.
