香芸火绒草Leontopodium haplophylloides精油化学成分的研究

香芸火绒草主要分布于我国西部的青海、四川、甘肃省地区。采其当年生茎、叶、花分别用水蒸馏法和萃取两种方法提取精油和浸膏，平均得率精油为0．1003％，浸膏为0．74％。经气相色谱．质谱联用技术分析，鉴定出愈创醇、3，7，11-三甲基．1．醇十二碳三烯-2,6，10、甲酸香草酯、苯二酸双酯、十六烷酸、姜黄烯、三环庚烯、芳樟醇、苯甲酸苯乙酯、苯乙醇乙酯、香叶醛、香草醇等22种化合物。另外，还对香芸火绒草浸膏香气作了香型评定，为清灵花香，香气甜润幽雅、珍贵，在日用化工、食品工业上都有较高的应用价值，该植物可成为天然香料生产一种新型的原料。

Study on Essential Oil Chemical Constituents from Leontopodium haplophylloides

The main distribution of Leontopiodium haplophylloides Hand-Mass is found grown in the west China or Qinghai, Sichuan, Gansu provinces. The essential oil and extractum are extracted from its stem, leaf and flower by steam distillation and solvent extraction. According to the analysis, it contains 0.1003% essential oil and 0.74% extraction in average. The chemical constituents of this essential oil have been identified by GS-MS. 22 kinds of components were separated. The main compounds are guaiacol, 3,7,11-trmethyl-1-ol-doclecatrien -2,6,10, vanillyl formate, diacidbenzene (2-ethylmethoxyl) diester, hexadecane acid, gurcumene, tricyc1oheptene, linalool, phenylethyl benzcate , ethylbenzyl carbinol, geranial, vanilly1alcohol etc. The aroma type of the plant has also been identified, as Qinglinghua aroma which is delicate, sweet and rare. It is very valuable in daily chemical and food industry. The plant will be a new raw materials source of nature perfume.
