采用顶空固相微萃取气质联用分析检测了白芷的挥发性香味成分,探讨了萃取时间、萃取温度对所鉴定出的化合物数量和百分含量的影响,确定了固相微萃取的优化条件为:萃取时间35min,萃取温度60℃,此时色谱共分离得到46种化合物,可鉴别出39种物质,其主要成分是茴香脑(37.84%),其它含量较多的成分是3-羟基-4,5-二甲基-2[5H]呋喃酮(22.09%)、壬基环丙烷(6.45%)、4-甲基安息香醛(3.16%)、2-羟基-4,6-二甲氧基苯乙酮(2.61%)、1-十二烯(2.44%)等。
The volatile components of Angelica dahuricae were determined by headspace solid-phase microextraction coupled with gas chromatography-mass spectrometry (GC-MS / MS). The effects of extraction time and extraction temperature on the amount and percentage of compounds identified were investigated. The optimal conditions The extraction time was 35min and the extraction temperature was 60 ℃ .A total of 46 compounds were isolated by chromatography. 39 kinds of compounds were identified. The main constituents were anethole (37.84%), and the other components were 3-hydroxy- (22.09%), nonylcyclopropane (6.45%), 4-methylbenzaldehyde (3.16%), 2-hydroxy- Acetophenone (2.61%), 1-dodecene (2.44%) and the like.
