大透骨消挥发油化学成分的GC-MS分析

Analysis of Chemical Constituents of Volatile Oil from Ganltheria forrestii Diels by GC-MS

目的:研究大透骨消挥发油的化学成分。方法:采用水蒸气蒸馏法提取大透骨消(花、叶)挥发油,叶挥发油得率为0.30%,花提取物得率为0.10%;应用气相色谱-质谱进行分离测定,结合计算机检索技术对分离的化合物进行鉴定,应用色谱峰面积归一化法测定各成分的相对含量。结果:在叶挥发油中共分离出204种成分,鉴定出23个化学成分,其主要成分为烷烃类及其含氧衍生物等,主要有对羟基苯甲酸甲酯,含量70.70%;花提取物中分离出132个成分,鉴定出12个成分,主要为乙酰水扬酸甲酯,含量82.64%。结论:大透骨消花挥发油成分证实其药理作用与传统民间用药疗效一致。

Objective： Chemical constituents of the volatile oil from Ganltheria forrestii Diels originated from Yunnan Province were studied.Methods： Two types of volatile oil were obtained by steam distillation of the foliage and flowers with extraction rate of 0.30% and 0.10% respectively.The chemical constituents of the volatile oil were analyzed by GC-MS,and their relative contents were determined by area normalization.Results： 204 compounds were separated from the foliage extraction,and 23 of them were identified,with Methylparaben accounting for the major proportion（70.70%）;132 compounds were separated from the flower extraction,and 12 of them were identified,with Methyl salicylate accounting for the major proportion（82.64%）.Conclusion： The constituents of the volatile oil from Ganltheria forrestii Diels confirm the curative effect of the traditional Chinese herb medicine.
