摘要:  利用常压水蒸气蒸馏提取贵州老鹰茶 (Litsea coreana Levl.Var.Lanuginose)的挥发性成分,挥发油得率 0.1%,利用 GC- MS技术对老鹰茶的挥发油进行了研究,从 Litsea coreana挥发油中鉴定出 32种成分,占挥发油组成的 95%,主要成分是正癸醛 (Decanal)含量 71.53%;其次是 10-烯-十—醛 (10- undecenal),含量 5.02%;壬醛 (n- nonaldehyde),含量 3.95%; copaene,含量 3.58%,正十二酸乙烯酯 (Dodecanoic acid,ethenyl ester),含量 2.63%。

Abstract:  The essential oil(1ml,0.1% yield)was obtained by steam distillation from the Lao Ying tea which was the dry tender leaves of Litsea chliuanchieneneie wild- growing in Guizhou.The GC/MS was used to analyse the composition of the essential oil among 35 compounds recorded by GC/MS whereas,32 compounds were indentified.The essential oil was found to be rich in decanal(71.53% );10- undecenal(5.02% );n- nonaldehyde(3.95% );Copaene(3.58% );Dodecanoic acid,etheny1 ester(2.63% ).
