GC/MS分析紫丁香花与叶中的挥发性化学成分

Analysis of Volatile Components From Flower and Leaf of Syringa Oblata Lindl. by GC/MS

摘要: 用同时蒸馏 -萃取装置分别提取紫丁香花和叶挥发性物质 ,测得紫丁香花挥发油的含量为 1 .80 % ,紫丁香叶挥发油的含量为 1 .2 6 %。用 GC/MS法分别从紫丁香花和叶挥发油中分离并确定出 1 6种和 2 3种化学成分 ,用峰面积归一化法通过化学工作站数据处理系统 ,得出各化学成分在挥发油中的相对百分含量。

Abstract: The simultaneous distillation-extractor is used for extracting the volatile substances in flower and leaf of Syringa oblata lindl. The average oil yields obtained from the flower and leaf are 1.80% and 1.26%, respectively. The sixteen and twenty-three species of chemical components in flower and leaf are identified by gas chromatography-mass spectrometry (GC/MS ). The contents of the identified compounds extracted from flower and leaf are 95.87% and 96.70% of the total volatile substances, respectively.
