摘 要:建立了丹聪颗粒中丹参素的含量测定方法:色谱柱为DiamonsilC18柱,(250mm×6.0mm,5um),流动相为乙腈-水-冰醋酸(9:160:1),流速为1.0ml/min,检测波长280nm.结果表明:该测定方法快速、准确、灵敏、重现性好,实际测定3批样品,丹参素在0.184—1.656ug范围内进样,线性关系良好(r=0.9994),平均加样回收率为97.91%,RSD%值为1.59%.The high performance liquid chromatography (HPLC) method was established for determination of propanoic acid in dancong granules. Chromatographic conditions were: column,Diamonsil C18 (250 mm × 6.0 mm, 5 um) ; mobile phase, acetonitrile-water-acetic acid (9 : 160 : 1 ) ; flow rate, 1.0 mL/min; the UV wavelength used for detector was 280 nm. The results proved that this method was rapid, accurate, sensitive,and reproducible. The good linear correlation was observed from 0. 184 ug to 1. 656 ug(r = 0. 9994) ,and the average recovery was 97.91% ,with a relative standard deviation of 1.59% .The results of detennination for 3 batches of samples were satisfactory.
