江香薷籽挥发油成分的GC-MS分析

GC-MS Analysis of Essential Oil from Mosla Chinensis Seeds

目的:分析江香薷籽挥发油中的化学成分。方法:采用水蒸气蒸馏法提取江香薷籽挥发油,用气相色谱-质谱法鉴定其化学成分,归一化法测定其相对含量。结果:共检出20个色谱峰,鉴定了其中17个化合物,占挥发油总量的99.06%。其主要化学成分为香荆芥酚(57.01%)、百里香酚(30.72%)、乙酸百里酚(2.56%)、乙酸香荆芥酚(2.14%)、α-石竹烯(1.62%)。结论:本研究可为进一步开发利用江香薷提供科学依据,并为江香薷药材质量标准的制订提供参考。

OBJECTIVE： To analyze the chemical constituents of the essential oil extracted from Mosla chinensis seeds. METHODS： The essential oil was extracted from Mosla chinensis seeds by steam distillation method and identified by GC-MS, and its relative content was determined using normalization method. RESULTS： A total of 20 chromatographic peaks were detected and 17 chemical compounds were identified, which made up 99.06% of the total essential oil content. The major chemical constituents were carvacrol（ 57.01% ）, tbymol（30.72 % ）, thymol acetate（2.56% ）, carvacrol acetate（2.14% ） and α- caryophyllene（1.62% ） . CONCLUSION： The results in our study provides scientific basis for further exploitation and utilization of Mosla chinensis and serves as reference for establishing quality standard of Mosla chinensis herbal medicine.
