摘要/Abstract

摘要： 以厚朴野生种和栽培种苞片刚裂开的花苞为试材，采用固相微萃取和气相色谱—质谱(GC/MS)分析技术对其进行香气成分和相对含量的测定，比较分析了花朵不同部位香气成分的差异。结果表明：厚朴野生种共有39种香气成分，雌雄蕊中26种，花瓣中22种，栽培种中75种香气成分，雌雄蕊中49种，花瓣中54种。萜烯类是两种厚朴花苞中最重要的香气化合物，莰烯、罗勒烯异构体混合物、石竹烯、芳樟醇是野生种和栽培种中共有的相对含量较高的香气成分。厚朴野生种和栽培种间以及同种厚朴雌雄蕊与花瓣之间的香气成分的种类和相对含量差异显著。

Abstract: The aroma components in flower bud samples of Magnolia officinalis wild and cultivated species whose bracts had just opened were studied by solid phase micro-extraction and GC/MS technology. The aroma components and their relative contents in different flower parts were compared and analyzed. The results showed that there were 39 components in M.officinalis wild species, 26 in pistils and stamens, 22 in petals. There were 75 components in M.officinalis cultivated species, 49 in pistils and stamens, 54 in petals. Terpenes were the major compounds in the flower bud of M.officinalis, camphene, (Z)-3, 7-dimethyl-1,3,6-octatriene, caryophyllene and 3,7-dimethyl-1,6-octadien-3-ol were identified in both wild and cultivated species and their relative contents were high. Both the aromatic compounds and their relative contents in M.officinalis wild and cultivated species were distinctly different, the aromatic compounds and their relative contents were also significantly different in pistils and stamens, petals of M.officinalis wild or cultivated species.

Key words: Magnolia officinalis wild species, cultivated species, flower parts, aroma components, GC/MS
