固相微萃取气质联用分析新疆雪菊的挥发性成分

目的：建立新疆雪菊挥发性成分的分析方法，鉴定其化学成分。方法：利用顶空固相微萃取技术（HS-SPME）吸附新疆雪菊中的挥发性成分。方法：色谱-质谱联用技术（GC-MS）分析鉴定，并用峰面积进行归一化定量。结果：从雪菊中共分离出54个峰，鉴定出其中的47种化学成分，占总峰面积的95.88%。雪菊中主要挥发性成分为3-蒈烯、1，3，8-对-薄荷三烯、α-柠檬烯、马鞭草烯醇、香芹酮等。结论：建立的方法分离度好，准确、可靠，为新疆雪菊挥发性成分的研究提供了分析方法。

Analysis of Volatile Compounds from Coriopsis ticntoria with Solid Phase Microextraction by GC-MS

Objective: To identify the volatile compounds in Coriopsis ticntoria. Method: Volatile compounds from C. ticntoria were isolated by headspace solid phase microextraction (HS-SPME) and identified and quantified by gas chromatography-mass spectrometry (GC-MS). A quantitative analysis in percent was performed by peak area normalization measurements. Fifty-four peaks in C. ticntoria were detected respectively. Species of chemical componens were identified by GC-MS. Result: The content of the identified compounds extracted from C. ticntoria was 95.88% of the total volatile substances, 3-carene, 1,3,8-p-menthatriene, D-limonene, verbenol, carvone were the most abundant volatile compounds released from C. ticntoria. Conclusion: The method is simple, rapid and sensitive, which could be used for determination of volatile compounds in C. ticntoria.
