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。 With simultaneous distillation - extraction device were extracted lilac flowers and leaf volatile substances, measured lilac flower volatile oil content of 1.80%, clove leaf volatile oil content of 1.26%. Sixteen and twenty-three chemical constituents were isolated and identified by GC / MS from the volatile oil of lilac and the leaves respectively. The chemical workstation data processing system was normalized by peak area, and the chemical constituents were determined in volatile oil Relative percentage.
