5种欧丁香鲜花香气成分的比较研究

为探明欧丁香的主要香气成分及比较不同欧丁香品种间主要挥发性物质的差异，采用顶空固相微萃取(HS-SPME)和气相色谱-质谱联用(GC-MS)技术分析5种欧丁香鲜花的芳香成分及其相对含量。从‘瓷蓝’中检测出49种芳香成分，从‘麦肯’中检测出41种芳香成分，从‘沙萱’中检测出49种芳香成分，烯萜类化合物是它们的主要芳香成分；从‘裘利’中检测出40种芳香成分，从‘莫斯加’中检测出46种芳香成分，烯萜类化合物和芳香烃类化合物为主要芳香成分。将‘瓷蓝’和‘裘利’、‘麦肯’和‘沙萱’、‘莫斯加’分为3种不同的香气类型，并推测出欧丁香的最主要香气成分为烯萜类化合物。

Comparative studies on aroma components and contents of five Syringa vulgaris

The main components of Syringa vulgaris were studied and the volatile components of different Syringa vulgaris were compared. The chemical constituents and relative contents of fragrance released from fresh flowers of 5 Syringa vulgaris were analyzed by means of head solid-phase micro-extraction (HS-SPME) with gas chromatography-mass spectrometry (GC-MS). The results showed that 49 compounds were identified in ‘Wedgewood Blue’, 41 compounds were identified in ‘Arch Mckean’, 49 compounds were identified in ‘Sensation’，ene terpenoids were their main aromatic components. 40 compounds were identified in ‘Charles Joly’, 46 compounds were identified in ‘Krasavitsa Moskvy’, ene terpenoids and aromatic hydrocarbons were their main aromatic components. ‘Wedgewood Blue’ and ‘Charles Joly’,‘Arch Mckean’and ‘Sensation’, ‘Krasavitsa Moskvy’ were divided into three different types, and infer ene terpenoids were the main aromatic components of Syringa vulgaris
