用化学和高效液相制备色谱方法分离制备了红景天属植物提取物中甙及甙元的标准物，标准品纯度分别由１％～２％和１％提高到９９％和９７％以上。
Reference standard is usually needed in HPLC analysis of natural products.Method for preparing reference standard of salidrocide and p tyrosol by chemical pretreatment and preparative HPLC was described in this paper.Salidrocide and p tyrosol obtained by this method have a purity of 99% and 97% respectively.
