摘要
目的:用GC-MS分析比较天山假狼毒叶、花和根中挥发性成分。方法:采用索氏提取法提取天山假狼毒叶、花和根中的挥发性成分,经GC-MS联用技术对挥发性成分进行分析鉴定,采用色谱峰面积归一化法计算各挥发性成分的含量。结果:结果共鉴定出179个挥发性成分,其中天山假狼毒叶中81个,相对含量占总挥发性成分总量的82.77%;花中108个,相对含量占总挥发性成分总量的82.85%;根中112个,相对含量占总挥发性成分总量的85.98%;三者共同含有挥发性成分33个,共有成分在叶子中占总挥发性成分的39.24%,在花中占总挥发性成分的35.86%,在根中占总挥发性成分的48.89%。其中(Z,Z)-9,12-十八碳二烯酸在天山假狼毒叶、花、根挥发性成分中相对含量都最高,分别为11.12%、9.8%、22.49%。结论:天山假狼毒叶、花、根挥发性成分接近,但在组分和含量上存在一定的差异。
Objective: To compare and analyze the chemical constituents of volatile oils extracted from the different parts( flowers,leaves and roots) of Stelleropsis tianschanica by chromatography-mass spectrometry( GC-MS). Methods: The volatile oil was extracted by diethyl ether-Soxhlet extraction method and analyzed by GC-MS with a capillary gas chromatographic column. The relative contents of the volatile compounds were calculated by chromatographic peak area normalization method. Results: Totally 179 volatile constituents in the different parts of Stelleropsis tianschanica were identified. Among them,81 compounds were identified in leaves,and the relative content accounted for 82. 77% of the total volatile compounds; 108 compounds were identified in flowers,and the relative content accounted for 82. 85% of the total volatile compounds; 112 compounds were identified in roots,and the relative content accounted for 85. 98% of the total volatile compounds. Totally 33 compounds existed in all the three parts,and the content accounted for39. 24% of the total volatile components in leaves,35. 86% in flowers and 48. 89% in roots. The relative content of( Z,Z)-9,12-octadecadienoic acid in leaves,flowers and roots of S. tianschanica was the highest,which accounted for 11. 12%,9. 8% and 22. 49%,respectively. Conclusion: The different parts of S. tianschanica have similar volatile components,while the specific substances and the contents are different.
