桂花(晚银桂、贵妃红和窈窕淑女)挥发性成分分析

目的:分析3种桂花的挥发性成分。方法:采用顶空固相微萃取和气质联用技术(HS-SPME-GC-MS),首次分析了桂花花的挥发性成分。结果:从晚银桂、贵妃红和窈窕淑女的花中共鉴定出66种组分。用峰面积归一化法测定了其相对含量,其相对含量分别占总挥发性组分峰面积的79.96%、71.83%和83.61%。结论:首次分析了不同品种桂花的挥发性成分,为进一步开发利用桂花资源提供依据。

On the volatile components in Osmanthus fragrans(Wanyingui,Guifeihong and Yaotiaoshunv)

Objective: To investigate the volatile constituents from 3 species flowers of Osmanthus fragrans Lour.Methods: The volatile constituents from the flowers of O.fragrans Lour.were analyzed by head-space solid microextraction,coupled with HS-SPME GC-MS for the first time.Results: 66 components were identified from the flowers of O.fragrans(Wanyingui),O.fragrans(Guifeihong) and O.fragrans(Yaotiaoshunv),the contents of which were determined respectively by peak area normalization method.The relative contents accounted to 79.96%、71.83% and 83.61% of peak area in the volatile group.Conclusion: The volatile constituents are investigated for the first time from different species,and it provides the basis for further development.
