摘要
目的建立小儿生血颗粒的质量标准。方法用薄层色谱法对处方中熟地黄、山药、大枣等进行定性鉴别;用紫外分光光度法对处方中硫酸亚铁进行含量测定,检测波长为509nm。结果该产品定性鉴别薄层色谱特征明显,专属性强;硫酸亚铁在0.5～2.5mg/mL范围内呈良好线性关系,r=0.9999,平均回收率为101.3%(RSD=1.48%,n=5)。结论所建立的薄层鉴别和含量测定方法准确可行,重复性好,可有效地控制小儿生血颗粒的质量。
Objective To establish a quality standard for Xiaoer Shengxue granules. Method SHU-Dihuang,yam, Chinese data in Xiaoer Shengxue granules were identified by TLC. Ferrous sulfate in the granule was determined by UV with wavelength at 509 nm. Results SHU-Dihuang, yam, Chinese data could be detected by TLC. Ferrous sulfate showed a good linear relationship at the range of 0.50-2.50 mg/mL, r=0.9999. The average recovery was 101.3% and RSD was 1.48% （n =5）. Conclusion The method is available with a good reproducibility and can be used for the quality control of Xiaoer Shengxue granule.
