摘要: 采用同时水蒸馏-萃取的方法(simultaneousdistillation-extractionSDE)提取大花红景天挥发油,并用毛细管气相色谱-质谱联用法(GC-MS),对所得挥发油进行化学成分分离和鉴定.经毛细管色谱分离出234个峰,共鉴定了其中54种成分。分析鉴定结果表明,大花红景天挥发性主要化学成分为2-甲基-2-丁烯醇,3,7-二甲基-1,6-辛二烯-3-醇,4-甲基苯酚,2,6-二甲氧基苯酚,二丁基邻苯二甲酸盐,2,6,10,14-四甲基-十六烷。

Abstract: The simultaneous distillation-extraction (SDE)of essential oil from dry roots of Rhodiola Crenulata was adopted.GC/MS was used for determination of the composition of essential oil. By capillary chromatography, 234 peaks were isolated,and fifty-four compounds of them were identified. The main chemical components were 2-methyl-2-Buten-1-ol, 3,7-dimethyl-1,6-Octadien-3-ol,4 -methyl-Phenol, 2,6-dimethoxy-Phenol, Dibutyl phthalate,2 ,6,10,14-tetramethyl-Hexadecane,etc.

Key words: Rhodiola Crenulata, essential oil, GC/MS
