目的修订中药材黄药子的质量标准。方法药材粉末的显微鉴别,选用合适的方法测定浸出物,采用高效液相色谱法测定薯蓣皂苷的含量。结果显微鉴别组织特征典型,根据检测结果,暂规定本品水溶性浸出物不得少于15.0%;含薯蓣皂苷应为0.12%～0.29%,薯蓣皂苷在0.01958μg～0.3916μg范围内与峰面积呈良好的线性关系,平均回收率为99.30%(RSD=0.8%,n=6)。结论所建立的质量标准方法可靠、准确、专属性强,可有效控制黄药子的质量。
Objective To revisit the quality standard of Chinese herbal medicine Huangpi. Methods The drug powder microscopic identification, selection of the appropriate method for the determination of extract, determination of diosgenin content by high performance liquid chromatography. Results Microscopic identification of tissue characteristics typical, according to the test results, the temporary provision of the product water-soluble extract not less than 15.0%; containing diosgenin 0.12% ~ 0.29%, diosgenin in the range of 0.01958μg ~ 0.3916μg with the peak area A good linear relationship was found with an average recovery of 99.30% (RSD = 0.8%, n = 6). Conclusion The established quality standard method is reliable, accurate and specific, which can effectively control the quality of xanthium.
