摘　　要：目的　对大花红景天挥发油的化学成分进行分析。方法　采用水蒸气蒸馏法提取大花红景天挥发油,并通过气相色谱—质谱(GC -MS)联用技术,对其中的化学成分进行分析鉴定。结果　通过计算机检索,鉴定了其中的4 5个化合物,占挥发油色谱峰总面积的96 .6 1 %。主要成分为正辛醇(2 0 .31 %)、牛儿醇(1 2 .86 %)、2 -甲基- 3-丁烯- 2 -醇(1 2 .0 7%)、3-甲基- 2 -丁烯醇(6 .6 9%)、十六酸(6 .4 3%)、亚油酸(5 .73%)、环癸烷(4.0 5 %)等。检出成分占挥发油总量的96 .5 6 %。结论　所用方法为大花红景天的合理利用提供了科学依据。s:OBJECTIVE To analyze the chemical constituents of the volatile oil from the root of Rhodiola crenulata. METHODS The volatile oil from roots of Rhodiola crenulata was extracted by steam distillation method,and analyzed by gas chromatography-mass spectrometry (GC-MS). RESULTS 45 compounds were identified, which represented 96.56% of the total GC peak area of the volatile oil. The main components were 1-octanol (20.31%), geraniol (12.86%), 2-methyl-3-buten-2-ol (12.07%), 2-buten-1-ol (6.69%), Hexadeccanoic acid (6.43%), linoleic acid (5.74%), cyclodecane (4.05%), etc. CONCLUSION The present study provide scientific bases for the Rhodiola crenulata exploitation in reason.
