摘　　要：采用顶空固相微萃取气质联用(SPME-GC-MS)的方法检测红银花与金银花新鲜花蕾和干花蕾的挥发性成分。4种花蕾样品共鉴定出67种挥发性物质,其中新鲜红银花与金银花分别检测出48种和46种,经烘干处理的干红银花与金银花分别检测出34种和37种。[3.2.1.0(1,5)]三环辛烷、β-芳樟醇、5-甲基-2-己醇和以及十六烷是4种样品共有的成分。其中红银花挥发性成分主要以烃类、醇酮类为主,β-芳樟醇含量显著高于金银花;样品在由新鲜到烘干这一过程中,烃类和酯类挥发性物质含量降低,醛类和醇酮类挥发性物质显著增加。The chemical components of volatile flavor compounds of fresh and dried honeysuckle were analyzed.The volatile constituents of them were compared and analyzed by Headspace Solid- Phase Micro extraction and gas chromatography-mass spectrometry.The results showed that 67 volatile compounds of these 4 flower buds were identified by this identification method.Forty-eight and 46 volatile compounds were detected among flesh honeysuckle and red honeysuckle;Thirty-four and 37 volatile compounds were identified among dried honeysuckle and red honeysuckle.In these samples,the dominant components were Tricyclo[3.2.1.0（1,5） loctane,beta-Linalool,5-methyl-2-hexanol and Hexadecane.Combined with the special volatile substances,formed their own aroma characteristics.Besides,the mainly volatile compounds of red honeysuckle are hydrocarbons,alcohols and ketones,the content of beta-Linalool is significantly higher than the honeysuckle.During the process from fresh to drying,hydrocarbon and esters of volatile compounds were decreased,aldehydes and alchols ketones volatile subatances were increased significantly.
