目的:分析比较陕西产黄连木果实和叶中的挥发性成分。方法:采用顶空固相微萃取法(SPME)提取黄连木果实和叶中的挥发性成分,用气相色谱-质谱技术(GC-MS)结合保留指数分析和鉴定化学成分。结果:从黄连木的果实和叶中分别鉴定出29种和17种挥发性成分,分别占总峰面积的95.30%和96.91%。黄连木果实和叶的共有成分13种。结论:陕西产黄连木果实和叶中挥发性成分在组成和含量上存在差异,它们的主要组分是萜类化合物,但黄连木果实以单萜(76.32%)类化合物为主,黄连木叶以倍半萜(65.42%)类化合物为主。
Objective: To analyze and compare the volatile components in the fruits and leaves of Pistacia chinensis. Methods: The volatile components were extracted from the fruits and leaves of Pistacia chinensis by headspace solid-phase microextraction (SPME). The chemical constituents were analyzed and identified by gas chromatography-mass spectrometry (GC-MS) and retention index. Results: 29 kinds and 17 kinds of volatile components were identified from fruits and leaves of Pistacia chinensis respectively accounting for 95.30% and 96.91% of the total peak area, respectively. Coptis wood and leaves of the common components of 13 species. CONCLUSION: There are differences in composition and content of volatile components in Coptis chinensis Franch and its leaves. The main components of them are terpenoids, but the main fruits of Coptis chinensis are monoterpene (76.32%), Sesquiterpene (65.42%) compounds based.
