10种产地小茴香果实挥发油成分分析

Analysis of Volatile Components from Ten Kinds of Origin in Foeniculum vulgare Mill Fruits

目的分析10种不同产地小茴香果实挥发油成分,并检测其成分相对含量.方法选用固相微萃取法萃取10种小茴香果实中的挥发油,通过气相色谱-质谱联用对小茴香果实中挥发油成分进行分析.结果从10种不同产地小茴香果实挥发油中鉴定出化学成分68个,其中共有相同成分9个、不同成分59个.主要成分都是反式茴香脑、胡椒酚甲醚、4-甲氧基-苯甲醛,占总成分的80%以上.结论不同产地小茴香果实挥发油化学成分差异较大,为小茴香的合理开发利用提供依据.

Objective To analyze volatile components from ten different origin in fruits Foeniculum vulgare Mill,and detection of their relative contents.Methods The volatile oil was extracted by solid phase microextraction and analyzed by gas chromatography-mass spectrometry.Results Among the volatile of ten samples,68 compounds were identified.9 compounds were same and other 59 compounds were different.But trans-anethole,methylchavicol and p-methoxybenzaldehyde were the main compositoin and the contents of them were above 80%.Conclusions The composition of the volatile oil from different regions are different.And this study provides a theoretical basis for the rational exploitation of Thymus mongolicus.
