摘要
目的用高效液相色谱法测定香附丸中芍药苷的含量。方法采用高效液相色谱法,ZORBAX SB-C18分析柱(250mm×4.6mm,5μm);流动相:甲醇-0.05mol·L^-1磷酸二氢钾溶液-三乙胺(28:72:0.5);检测波长:230nm;流速:1.0ml·min^-1,柱温:40℃。结果芍药苷在0.44~3.96μg范围内的线性关系良好(r=0.9999),平均加样回收率为98.93%(n=5),重现性试验RSD为0.70%(n=5)。结论方法准确,灵敏度高,重现性好。
Objectivo: To detect the paeoniflorin content of Xiangfu Pills by RP - HPLC. Methods : RP - HPLC is adapted on ZORBAX SB - C 18 (250mm×4. 6mm, 5um) ; the mobile phase consisting of methanol and potassium dihydrogen and triethylamine (28 : 72 : 0. 5) ; the detection wavelength : 230nm; the flow rate: 1. 0 ml. min - 1 ; the column temperature: 40c. Results : There exists a good liner relationship in the range of 0. 44 - 3. 96ug ( r = 0. 9999), the average sample recovery rate is 98. 93% (n =5), and the relative standard deviation is 0. 70% (n =5). Conclusions: The method ofRP - HPLC is accurate, sensible and reproducible.
