云南清香木绿叶和嫩红叶挥发性成分对比研究

Study on the volatile Component of Green and Red Leave of the Pistacia weinmannifolia

[目的]对比云南清香木绿叶和嫩红叶中的挥发性成分。[方法]采用同时蒸馏萃取(SDE)和气相色谱-质谱(GC-MS)联用法分析比较清香木绿叶和嫩红叶中的挥发性成分,采用峰面积归一化法计算各成分的质量分数。[结果]从绿叶挥发油中鉴定出了114个化合物,嫩红叶挥发油中鉴定出144个化合物。[结论]清香木叶挥发油主要含萜烯类化合物,绿叶和嫩红叶挥发油中有43种成分是相同的,但含量变化较大。

[ Objective ] The volatile component of green and red leave of the Pistacia weinmannifolia were studied. [ Method ] In the present study, the volatile oil of green and red leave of the Plstacia weinmannifolia were extracted by simultaneous distillation and extraction（SDE）, followed by the analysis with gas chromatography - mass spectrometry （GC-MS）. The relative contents in the volatile oil were determined by area normalization. [ Result] The volatile oil of green leave has 114 compounds while the other oil has 144 compounds. [ Conclusion]43 com- pounds in the two kinds of volatile oil were same, but their contents were varied greatly. Most of the compounds in the both kinds of the vola- tile oil were terpene compounds.
