| 摘 要： | 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。

| Abstract: | Aroma components of angelica were analyzed by HS-SPME and GC-MS. Effect of extraction time and temperature on the number of identified compounds and total mass fraction were also discussed for the optimal SPME conditions ： extraction time 35 min, extraction temperature 60℃.46 kinds of compounds were separated by the Gas Chromatography and 39 of these could be determined under the certain conditions above with the results as follows： the main component was anethole （37.84%） and other components of high content were 3 - hydroxy-4,5 - dimethyl - 2 [SH]-furanone（22.09%）, nonyl cyclopropane（6.45%）, 4- methyl- benzoic acid （3.16%）, 2 - hydroxy -4,6 - dimethoxy acetophenone （2.61%）, 1 - dodecene （2.44%） and so on. |
