黄杞叶挥发油化学成分的GC-MS分析

目的:研究黄杞叶的挥发油成分。方法:采用水蒸气蒸馏法提取黄杞叶中的挥发油,并通过气相色谱-质谱(GC-MS)联用仪对其化学成分进行分析和鉴定,用色谱峰面积归一化法计算各组分相对百分含量。结果:从黄杞叶挥发油中共分离出55个组分,鉴定了其中33个化合物,占总量的95.0%,主要成分为十六烷酸(hexadecanoic acid,44.73%)、叶绿醇(phytol,14.71%)、十八碳-9,12,15-三烯醛(9,12,15-octadecatriena,12.24%)等。结论:分析结果可为黄杞叶的质量控制提供依据,并为提高黄杞叶的进一步开发利用提供参考。

GC-MS Analysis of Chemical Components of Volatile Oil from Leaves of Engelhardtia roxburghiana

Objective: To analyze the volatile oil from the leaves of Engelharditia roxburghiana . Method: The volatile oil was extracted from leaves of E. roxburghiana by steam distillation, the amount of the components from the volatile oil was separated and identified by GC-MS, and the relative content of each component was calculated by area normalization method. Result: Fifty five compounds were separated by GC and 33 of them were identified, which accounted for 95% of volatile oil. The major components were hexadecanoic acid (44.73%), phytol (14.71%), 9,12,15-octadecatriena (12.24%) et al. Conclusion: The analysis results can provide evidence for quality control and further exploitation of leaves of E. roxburghiana .
