摘要：[目的]本研究明确2种浓香型石斛花朵的香气成分及其含量,探明其香气组成,以期为石斛花的保健开发提供参考。[方法]采用顶空固相微萃取(HS-SPME)结合气相色谱-质谱联用(GC-MS)技术,分析了2种浓香型石斛花朵的挥发性成分。[结果]发现细叶石斛花含挥发性成分52个,翅梗石斛花含挥发性成分35个,主要成分皆为烯烃类。[结论]首次测定了翅梗石斛新鲜花朵的挥发性成分,其特征香气成分为罗勒烯、β-石竹烯和d-柠檬烯。细叶石斛花的特征香气成分为罗勒烯、β-石竹烯、芳樟醇。
[Objective]To analyze the aroma components and the relative contents in the flowers of two Dendrobium species,D.hancockii and D.trigonopus.[Method]The volatile constituents and their contents were analyzed by solid-phase microextraction(SPME)and gas chromatography-mass spectrometry(GC-MS).[Result]For the first time,the volatile constituents were analyzed in fresh flowers of D.trigonopus and thirty-five compounds were characterized.Fifty-two compounds were characterized in D.hancockii.The main volatile constituent in both the two species was olefin.[Conclusion]The characteristic aroma components are(Z)-β-Ocimene,β-Caryophyllene and Linalool in D.hancockii flower.The characteristic aroma components are(Z)-β-Ocimene,β-Caryophyllene and d-(+)-Limonene in D.trigonopus flower.
