翟少钦曹国文李成君 重庆市畜牧科学院兽医研究所，重庆402460 摘要：目的：建立控制复方黄罠金银花颗粒的质量标准。方法：采用薄层层析对颗粒中女贞 子、金银花、黄罠、枸杞子进行了薄层鉴别；采用双光束紫外-可见光分光度法测定了颗粒 中绿原酸的含量。结果：薄层鉴别方法专属性强，- 具有良好的线性关系，标准曲线回归方程为：A=- (r=, n=5)；样品 在24h内稳定，RSD=%；%, RSD=%；该方法精密度 高，RSD=%o结论：本质量标准可有效地控制复方黄罠金银花颗粒的质量。 关键词：黄罠金银花颗粒；薄层色谱法；紫外分光光度法；绿原酸；
Study the standard of Huangjin Compound granules Zhai shaoqin Cao guowen Li chengjun Chongqing Academy of Animal Science, Chongqing 402460, China Abstract: Objective: Establish control standards of Huangjin compound granules. Methods: Using the Thin layer chromatography to distinguish Astragalus mogholicus, Lonicera japonica, Ligustri lucidi Fructus, Chinese wolfberry fruit, etc. in the par ti cles. Dual-be am UV 一 visible spec tr oph otometry in the det ermina tion of the particle content of chlorogenic acid. ResuIts: TLC method is specific・ Determination of chlorogenic acid has good linearity within the the 42. 24-84. 48Ag / ml . The Standard curve regression equation: A=0. 0053XC —0. 0012 (r=0. 9999, n=5). The Sample is stable in the 24h, RSD=0. 733%. The average recovery is %, RSD=0. 499%. This method was high Precision, RSD=%. Conclusion: The quality st andards that can effec ti vely cont rol the qual ity of Huang jin compound granules. Keywords: Huang jin compound granules , TLC, Dual-beam UV-visible
