五指毛桃香气挥发性成分分析

Analysis of aroma components in the Ficus hirta Vahl

本研究的目的是分析五指毛桃香气中挥发性物质的主要化学成分。方法是采用静态顶空进样技术,对五指毛桃的香气挥发性成分进行采集,结合气相色谱-质谱联用仪对这些成分进行检测。然后,结合美国国家标准与技术局化学数据库(NIST2014)对检测结果进行检索,得出五指毛桃的香气挥发性成分主要包括醛类、酯类、烯烃、烷烃、醇类和酸类,其中醛类、酯类和烯烃类是构成香气成分的主要物质。结论:利用静态顶空技术可以成功鉴定五指毛桃香气挥发性物质的主要成分,体现了该技术应用范围广泛且实用性强,同时也为五指毛桃香气挥发性成分的研究提供了一种新方法。

The objective of this studyis to analyze the aroma components of the Ficus hirta Vahl.The aroma components of Ficus hirta Vahl was collected by static headspace sampling technique and deteced by gas chromatography-mass spectrometry(GC-MS).Then,combining GC-MS analysis with NIST2014 database search,we can analyze the aroma components of Ficus hirta Vahl which mainly included aldehydes,esters,olefins,alkanes,alcohols and acids.Among these components,aldehydes,esters and olefins were the critical ones which contributed to aroma components of Ficus hirta Vahl.CONCLUSIONS:Static headspace technique was successfully used to identify the main components of volatile substances in the Ficus hirta Vahl,which showed that this techniquehas the characters including wide range,good practicability and so on.Meanwhile,it also provides a new method for the study of aroma components of the Ficus hirta Vahl.
