【摘要】 [目的]对藏角蒿花中挥发油的化学成分进行研究。[方法]采用水蒸气蒸馏法提取藏角蒿花中的挥发油,用毛细管气相色谱—质谱联用技术(GC-MS)对其化学成分进行分析,以面积归一法测定各个成分的相对百分含量。[结果]共分离出24个峰,鉴定了其中23个化学成分,占挥发油总量的99.59%。[结论]藏角蒿花中挥发油的主要成分为十六酸(31.66%)、二十三烷(15.76%)、9-己基十七烷(8.37%)、十四酸(7.96%)、2,15-十六烷二酮(7.20%)等。更多还原

【Abstract】 [Objective] The research aimed to analyze the chemical components of the volatile oil in blossom of Incarvillea younghusbandii Sprague.[Method] The volatile oils of Incarvillea younghusbandii Sprague were extracted by water steam distillation method and its chemical components were separated and identified by GC-MS.The content of each component was determined by area normalization method.[Result] Twenty four peaks were separated and twenty three components were identified,which constituted about 99.59% of the total volatile oils.[Conclusion] The main compounds of the volatile oil in blossom of Incarvillea younghusbandii Sprague were hexadecanoic acid(31.66%),tricosane(15.76%),9-hexyl-heptadecane(8.37%),myristic acid(7.96%),2,15-hexadecanedione(7.20%).更多还原
