摘 要:目的:建立益心片(人参、黄芪、川芎、五味子,丹参等)的质量标准。方法:用TLC法对人参、黄芪、川芎、五味子进行了定性鉴别;用HPLC法测定了益心片中丹酚酸B的含量。结果:定性鉴别分离度好,专属性强;丹酚酸B的含量测定中样品以100倍甲醇为溶媒,超声30min,在C18柱上以乙腈旬.05%磷酸为流动相梯度洗脱,在波长280nm处检测。丹酚酸B在0.12504~2.50080μg范围内线性关系良好,r=0,9999,平均加样回收率为99.35%,RSD为1.02%。结论:方法简便准确、灵敏度高,可用于益心片的质量控制。Objective:To determine the quality standard of Yixin Tablet. Methods: The nature differentiation of Radix Ginseng, Radix Astragali, Rhizoma Chuanxiong, Fructus Schisandrae was determined by TLC and content of salvianolic acid B in Yixin Tablet was determined by HPLC. Results: The nature differentiation separate degree is kind and special attribute was strong. The compounds were base-isolated on the column of C18 which gradient eluted with acetonitrile and H2O(0. 05% H3PO4 ) and detective wavelength was 280nm. The lineafity was obtained over the range of 0. 12504-2. 50080 I.Lg ( r = 0. 9999) and the average recovery rate was 99. 35%. Conclusion : The method is simple, convenient and accurate. The sensitivity is high. It can be used in the quality control of Yixin Tablet.
