广西产龙眼叶及花挥发油成分气质联用分析

Study on Chemical Constituents of Volatile Oil from Leaves and Flowers of Dimocarpus longan in Guangxi by GC/MS

目的：采用GC/MS分析广西产龙眼叶及花挥发油的成分。方法：采用水蒸气蒸馏法分别提取广西产龙眼叶和龙眼花中的挥发油,并通过GC/MS技术对龙眼叶和龙眼花的挥发油成分进行分析。结果：龙眼叶和龙眼花挥发油得率分别为0.35%和0.20%,龙眼叶挥发油共鉴定出了39个化合物,占挥发油总成分的96.2%;龙眼花挥发油共鉴定出了32个化合物,占挥发油总成分的97.01%。结论：该法简便、快速、灵敏度高,为合理使用龙眼叶和花提供一定的科学依据。

Objective：To Analyze the chemical constituents of volatile oil from the leaves and flowers of Dimocarpus longan in Guangxi.Method：The volatile oil was extracted from the leaves and flowers of D.longan.by steam distillation.The constituents of volatile oil were identified by GC /MS technology.Result：The yield of the collected volatile oil of the leaves and flowers of D.longan was 0.35%,0.20%,repectively.39 compounds constituting 96.2% of the oil of leaves were identified.32 compounds constituting 97.01% of the oil of flowers were identified.Conclusion：The GC /MS is a simple,rapid and sensitive method.It can provide a scientific basis for rational use of the leaves and flowers of D.longan in Guangxi.
