目的:分析苍耳子生品及炒制品中挥发性成分的化学成分及相对含量的变化。方法:采用顶空固相微萃取法(HSSPME)结合气相色谱-质谱(GC-MS)联用技术对苍耳子的生品及炒制品挥发性成分进行分析;以峰面积归一化法计算各组分的相对百分含量。结果:从苍耳子生品和炒制品中分别分离鉴定出26种和27种化合物,共有成分19种,分别占挥发性成分总量的68.69%和90.08%,其中生品含量较高的成分有桉叶油醇(15.3%)、樟脑(9.6%)、冰片(6.89%)等,炒制品中成分含量较高的成分有薄荷醇(24.09%)、冰片(18.48%)、桉叶油醇(7.19%)等。结论:炒制品中薄荷醇、冰片等具有治疗鼻炎作用的相对含量较生品有明显提高,采用HS-SPME-GC-MS联用技术分析苍耳子生品及炒制品中挥发性成分及相对含量变化,可以从挥发性成分的变化方面为苍耳子生品及炒制品的功效差异的物质基础奠定一定的理论基础,为其进一步研究和综合利用提供科学依据。
Objective: To analyze the changes of the chemical components and relative contents of the volatile components in the raw and fried products of Xanthium ssp. Methods: The volatile components of raw and fried products of Xanthium sibiricus were analyzed by headspace solid-phase microextraction (HSSPME) combined with gas chromatography-mass spectrometry (GC-MS). The peak area normalization The relative percentage of each component. Results: 26 kinds and 27 kinds of compounds were isolated and identified respectively from the raw and fried products of Xanthium sibiricum, with 19 kinds of common components accounting for 68.69% and 90.08% of the total volatile components respectively. Among them, the components with higher contents of raw materials There are eucalyptol (15.3%), camphor (9.6%), borneol (6.89%) and so on. The higher ingredients in the fried products are menthol (24.09%), borneol (18.48%), eucalyptol (7.19%) and so on. Conclusions: The relative contents of menthol and borneol in the treatment of rhinitis were significantly higher than those of the raw product, and the volatile components in the raw and fried products of Xanthium sibiricum were analyzed by HS-SPME-GC-MS Content changes, we can lay a certain theoretical foundation for the material basis of the differences in the efficacy of the cocklebur seeds and fried products from the aspects of the volatile components, and provide a scientific basis for further research and comprehensive utilization.
