摘要: 采用水蒸气蒸馏法对兴安杜鹃叶中的挥发性成分进行提取,并运用气相色谱—质谱联用技术(GC-MS)对其挥发性成分进行了系统的分离和鉴定。从兴安杜鹃叶中共鉴定出54种挥发性成分,占总馏出成分的97.84%。兴安杜鹃叶主要挥发性成分为桉叶醇(eduesmol),相对含量10.95%;β-愈创木烯(β-guaiene),相对含量10.21%;长叶醛(longifolenaldehyde),相对含量7.88%;1,5,9,9-四甲基-1,4,7-环十一碳三烯(1,5,9,9-tetramethyl-1,4,7-cycloundecatriene),相对含量7.80%;杜鹃酮(germacrone),相对含量5.91%;(-)-葎草烯环氧化物Ⅱ((-)-Humulene epoxide Ⅱ),相对含量5.52%;2-庚基-1,3-二氧戊环(2-heptyl-1,3-dioxolane),相对含量4.99%;石竹烯(caryophyllene),相对含量3.70%;(+)-γ-古芸烯((+)-γ-gurjunene),相对含量3.44%。

Abstract: The volatile components of the essential oils from the leaves of Rhododendron dauricum L. were extracted by steam distillation and then analyzed by GC-MS. Total of Fifty four volatile components were identified, composed of 97.84% of total essential oil. The major volatile components are: eduesmol, relative content 10.95%; β-guaiene, relative content 10.21%; longifolenaldehyde, relative content 7.88%; 1,5,9,9-tetramethyl-1,4,7-cycloundecatriene, relative content 7.80%; germacrone, relative content 5.91%; (-)-Humulene epoxide Ⅱ, relative content 5.52%; 2-heptyl-1,3-dioxolane, relative content 4.99%; caryophyllene, relative content 3.70%; (+)-γ-gurjunene, the relative content 3.44%.
