基于HS-SPME/GC/MS的姜花不同部位挥发性成分分析

Analysis on volatile components in different parts of Hedychium coroarium by HS-SPME/GC/MS

采用顶空—固相微萃取法提取姜花根、茎叶、花3个部位的挥发性化学成分,并用GC-MS法对其进行分析与鉴定,通过峰面积归一化法得出各成分在组分中的相对含量。结果表明:从姜花中分别鉴定出57,63,60种化合物,其中共有成分36种,占各部位挥发性成分相对含量的83.864%,66.624%,86.912%。姜花3个部位得到的挥发性成分大多为萜类化合物,且β-蒎烯在根、茎叶和花中的含量都相对较高。

The volatile components were extracted and identified by solid phase microextraction combined with gas chromatography-mass spectrometry(HS-SPME-GC/MS),and the relative content of components were analyzed by area normalization.The results showed that 57,63,and 60 kinds of compounds were identified from the roots,stems and leaves,and flowers of H.coroarium,accounting for 83.864%,66.624%,86.912%of the total volatile components,respectively.Among which 36 kinds of were common.The content ofβ-pinene in the three parts was relatively high.Most of the volatile components isolated from ginger roots,stems and leaves,flowers are mites.In the development and utilization of raw materials and flavors and fragrances in the pharmaceutical industry,the relative content of H.coroarium components has played a guiding role.
