摘要:

研究佛手精油的挥发性物质和关键香气成分。佛手经水蒸气蒸馏法提取精油,利用气相色谱-质谱(gaschromatography-mass spectrometer,GC-MS)结合气相色谱-嗅闻(gas chromatography-olfactometry,GC-O)技术对挥发性物质和香气成分进行分析。GC-MS-O检测出36 种挥发性物质,主要成分为D-柠檬烯(34.69%)、γ-松油烯(20.42%)、β-甜没药烯(4.59%)。采用稀释法和强度法分析发现D-α-蒎烯、D-柠檬烯、β-芳樟醇、别罗勒烯、4-松油醇、α-佛手柑烯具有较大的香气强度;D-α-蒎烯、β-蒎烯、β-罗勒烯、橙花乙酸酯、α-佛手柑烯具有较大风味稀释因子。综合分析认为D-α-蒎烯和α-佛手柑烯是佛手精油的关键特征香味成分。

Abstract:

The volatile constitutes and odorous compounds in essential oil of finger citron (Citrus medica L. var.
sarcodactylis Swingle) were evaluated. The oil was extracted by hydrodistillation and analyzed by gas chromatographymass
spectrometry (GC-MS) and gas chromatography-olfactometry (GC-O). A total of 36 compounds in the oil were
identified, among which, D-limonene (34.69%), γ-terpinene (20.42%), and β-bisabolene (4.59%) were the main compounds.
D-α-pinene, D-limonene, β-linalool, allo-ocimene, terpin-4-ol and α-bergamotene displayed strong aromatic intensity,
while D-α-pinene, β-pinene, β-ocimene, neryl acetate and α-bergamotene showed relatively higher flavor dilution (FD)
factor. The results demonstrated that D-α-pinene and α-bergamotene were the key contributors to the characteristic
aroma of finger citron oil.

Key words: finger citron essential oil, odorous compounds, gas chromatography-mass spectrometry (GC-MS), gas chromatography-olfactometry (GC-O)
