红景天挥发油的化学成分研究

目的 :对云南红景天挥发油的化学成分进行了研究。方法 :采用水蒸气蒸馏法提取红景天挥发油 ,以气相色谱 质谱 计算机 (GC MS DS)联用技术 ,对挥发油的化学成分进行了分析鉴定。结果 :分离出约 90个峰 ,鉴定了其中的 4 4个化合物 ,占挥发油色谱峰总面积的 87.93%。结论 :云南红景天主要成分为正辛醇 (2 8.2 5% )、牛儿醇 (2 1.92 % )、里哪醇 (8.34% )、桃金娘醇 (4 .6 6 % )、正葵醇 (4 .0 9% )及橙花醇乙酸酯 (3.52 % )等

Studies on the chemical constituents of the essential oil from Rhodiola yunnanesis

Objective: To study the chemical constituents of the essential oil from Rhodiola yunnanesis. Methods: The essential oil was extracted by steam distillation. The chemical constituents of the essential oil were analyzed by GC MS DS. Results: More than 90 peaks were separated and 44 of them were identified,which represented 87.93% of the total GC peak areas of the essential oil. Conclusion: The major components of the essential oil from Rhodiola yunnanesis are 1 octanol ( 28.25% ), geraniol (21.92%), linalol (8.34%), myrtenol (4.66%), decanol (4.09%), nerol acetate (3.52%),etc. [
