Abstract

The aim of this study was to identify and characterize the aroma components of absolute oil from natsudaidai (Citrus natsudaidai Hayata) flowers. A total of 43 aroma components were detected in the absolute oil of natsudaidai flowers using a headspace solid phase microextraction (SPME)-gas chromatography-mass spectrometry (GC-MS). The most abundant components from the absolute oil was linalool (31.14%), followed by methyl anthranilate, γ-terpinene, p-cymene, (E)-β-ocimene, limonene, indole and α-terpineol. The configuration of linalool from the absolute oil was assigned as (S)-form and its optical purities were determined as 89.36±0.36% enantiomeric excess using a SPME-chiral GC. These results indicated that the composition of aroma components in the absolute oil would influence the overall aroma qualities of natsudaidai flowers and the physiological effects on human.

摘要

本研究旨在鉴定和分析柚子花（Citrus natsudaidai Hayata）精油的香气成分。采用顶空固相微萃取（HS-SPME）-气相色谱-质谱联用技术（GC-MS）检测柚子花精油中的香气成分，共鉴定出 43 种香气成分。从柚子花精油中分离出的主要成分为芳樟醇（31.14%），其次为甲基氨基苯甲酸甲酯、γ-萜品烯、对伞花烃、（E）-β-罗勒烯、柠檬烯、吲哚和α-松油醇。从柚子花精油中分离出的芳樟醇构型为（S）-型，其光学纯度采用 SPME-手性 GC 法测定为 89.36±0.36%对映体过量。这些结果表明，精油中香气成分的组成会影响柚子花的整体香气品质和对人体的生理作用。
