摘要:
目的:分析不同产地香荚兰豆挥发性成分的组成。方法:采用顶空固相微萃取-气相色谱-质谱联用技术,结合惠普-化学源化学工作站对不同产地的香荚兰豆中挥发性化学成分进行定性分析,以峰面积归一化法计算各组分的相对含量,并通过主成分分析和聚类分析2 种化学计量法对数据进行分析。结果:初步鉴定出104 种化合物,不同产地香荚兰豆挥发性成分有一定差异。结论:此方法稳定可靠,适用于香荚兰豆挥发性成分的快速分析,可为香荚兰豆的质量评价提供一定的科学依据。

Abstract:
Objective: To analyze the volatile components of vanilla beans from different habitats. Methods: The contents of volatile components from vanilla beans were determined by peak area normalization method. The separated volatile components were identified by GC-MS. Results: Totally 104 volatile components were identified preliminarily. There were differences in volatile components of vanilla beans from different habitats. Conclusion: The analytical method presented in this study is reliable and stable and can be applied for the analysis of volatile components of vanilla beans.
Key words: vanilla bean, volatile components, headspace solid phase micro extraction, cluster analysis, principal component analysis
