大叶含笑叶精油化学成分研究

STUDY ON THE CHEMICAL CONSTITUENTS OF THE ESSENTIAL OIL FROM MICHELIA FALLAXA DANDY LEAF

用毛细管气相色谱保留指数法和标准样品叠加法以及色谱-质谱-计算机联用技术分析了大叶含笑(Michelia fallaxa Dandy)叶精油的化学成分。从45m×0.25mmOV-101弹性石英毛细管柱分离出来的58个色谱峰中,鉴定出44个成分,占该挥发油总量的95.69％。其主要化学成分是橙花叔醇(12.83％)、β-石竹烯(10.11％)、金合欢醇(8.17％)、愈创木醇(7.86％)、乙酸香叶酯(4.32％)、乙酸松油酯(3.62％)、β-蒎烯(3.58％)以及3-己烯-1-醇、别香树烯、δ-榄香烯、榄香醇、榄香素等。

Chemical constituents of the essential oil from leaf of Michelia fallaxa Dandy were compared with authentic samples on GC and analyzed by GC/MS/DS technique. Among the 58 constituents separated, 44 components,which make up 95.69% of the total oil,were identified. The major components are nerolidol (12.83%),β-caryophyllene (10. ll%),farnesol (8.17%),guaiol (7. 86%),geranyl acetate (4.32%),ter-pinyl acetate (3.62%), β-pinene (3. 58%), and 3-hexen-l-ol, alloaromadendrene, δ-elemene, elemol, elemicin.etc.
