Analysis of Chemical Constituents of Volatile Oil from Yunnan Weigela florida

目的:研究云南产锦带花挥发油的化学成分。方法:采用水蒸气蒸馏法提取锦带花挥发油,利用气相色谱-质谱联用技术进行化学成分分析。结果:共分离出16种化学成分,包含有机酸、烷烃、酚类和酮类。其中含量最高的是十六烷酸(53.048%),其次是亚油酸(9.654%)、正二十五烷(8.967%)、正二十七烷(8.555%)、正二十三烷(5.665%)和亚麻酸(3.848%)。结论:本研究首次报道了云南产锦带花的挥发油化学成分,可为锦带花的进一步高效合理使用提供科学依据。

OBJECTIVE： To study the chemical constituents of the volatile oil from Yunnan Weigela florida. METHODS ： The volatile oil was extracted by steam distillation, and identified by GC-MS. RESULTS： 16 compounds were isolated, including organ- ic acid, alkane, phenols and ketone. The content of palmitic acid was the highest （53.048%）, followed by linoleic acid （9.654%）, pentacosane （8.967 % ）, heptacosane （8.555 % ）, tricosane （5.665 % ） and linolenic acid （3.848 % ）. CONCLUSION： The study report the chemical constituents of volatile oil from Yunnan W. florida for the first time and provide scientific basis for the further effective utilization of W. florida.
