摘　　要： 结合大孔树脂富集、柱色谱分离纯化法,研究了从大花红景天醇提取物中制备大花红天素标准品的方法。标准品通过波谱学方法进行了结构鉴定,用归一化法定量,质量分数大于99%。所得大花红天素可作为大花红景天原料及其产品定性、定量分析使用的标准品。 A method for preparation of crenulatin reference substance was developed in this paper. Crenulatin was extracted from the roots ofRhodiola Crenulata. H by alcohol, isolated by macroporousresin, purified by column chromatography, and structurally analyzed by spectroscopy. GC-MS analysis showed that the contents of crenulatin were higher than 99%. The achieved crenulatin could be used as reference substances for the qualitative and quantitative analysis of the raw materials and products ofRhodiola Crenulata. H.
