【摘要】 目的 建立白花蛇舌草质量控制方法。 方法 采用生药学方法对白花蛇舌草及其伪品水线草和纤花耳草进行鉴别，并建立了白花蛇舌草中齐墩果酸的薄层扫描含量测定方法。 结果 白花蛇舌草中的齐墩果酸在0.8～6.4μg间有良好的线性关系，回收率为98.7%，RSD为1.95%(n=5)。 结论 将生药学研究方法和白花蛇舌草中的齐墩果酸的含量测定方法相结合，可作为质量控制方法。

    【Abstract】 Objective To establish the method of quality control of Oldenlandia Diffusa(willd.)Roxb.Methods The content of oleanolic acid in Oldenlandia Diffusa(willd.)Roxb was determined by TLC-scanning to discriminate its counterfeit such as Oldenlandia corymbosa L.and Hedyotis tenelliflora BL.Results The relationship between Oldenlandia Diffusa(willd.)Roxb and its oleanolic acid content during0.8and6.4μgwas very linear when the recovery rate of adding sample was98.7% ......
