摘要: 采用SDE提取精油,用气-质联用技术,分析了重庆产特级和一级珠兰花茶及其素坯的挥发油化学组成。在特级和一级珠兰花茶中分别检测出57个组分。其中有19个香气化合物是素坯中没有的,新增香气化合物在一级珠兰花茶中相对含量为40.27%,特级珠兰花茶中相对含量达到81.84%。主要香气化合物有:大根香叶烯B(特级28.25%、一级5.47%)、γ-榄香烯(特级13.04%、一级6.11%)、别香橙烯(特级8.11%、一级13.26%)、茉莉酮酸甲酯(特级9.04%、一级5.55%)、δ-杜松烯(特级7.68%、一级0.60%)、γ-蛇麻烯(特级3.32%、一级0.42%)、肉豆蔻醚(特级2.61%、一级1.08%)。

Abstract: The volatile oils of Zhulan scented teas and their dhools were extracted with simultaneous steam distillation extract(SDE) as well as analyzed and identified by GC-MS. Fifty-seven constituents had been identified from the volatile oils respectively. There were 19 volatiles in Zhulan scented teas which did not exist in dhools. The relative contents of newly absorbed volatiles were 40.27% and 81.84% in the first grade and special grade Zhulan scented tea respectively. The key constituents were germacrene B,γ-elemene, alloaromadendrene, methyl jasmonate, δ-cadinene,γ-selinene, myristicin.

Key words: volatile oils, constituents, dhool, Zhulan scented tea
