摘要
目的建立浓缩六味地黄丸中马钱苷、芍药苷的含量同时测定方法。方法采用高效液相色谱法,色谱柱为Hypersil C18(200 mm×4.6 mm,5μm),Nova-PakC18 Guard-PakTM保护柱;流动相:0.05%磷酸水溶液-乙腈进行梯度洗脱;柱温:30℃;流速:1 mL/min。结果马钱苷在0.11~1.10μg范围内,进样量与峰面积线性关系良好(r=0.999 5);样品的平均回收率为99.2%,RSD为1.3%(n=5)。芍药苷在0.15~1.50μg范围内,进样量与峰面积线性关系良好(r=0.999 2);样品的平均回收率为100.4%,RSD为1.9%(n=5)。结论此方法简便、快速,可作为浓缩六味地黄丸中马钱苷、芍药苷的含量同时测定方法。
Objective To establish a determination method of loganin and paeoniflorin for Liuwei Dihuang pill. Method There were the stationary phase with Hypersil C18 (200 mm×4.6 mm 5 μm) Nova-PakC18 Guard-PakTM, 0.05% phosphoric acid solution(A)-acetonirtile(B), The photodiode array detector at 233nm, column temperature 30℃ and the flow rate 1 mL/min in HPLC. Result For loganin, the calibration curve 0.999 5), the average recovery of the method was linear over the range of 0.11-1.10 μg (r= was 100.1% , RSD =3.0% (n =5). For paeoniflorin, the calibration curve was linear over the range of 0.15-1.50 μg (r=0.999 2), the average recovery of the method was 100.7%,RSD=2.1%(n=5). Conclusion The method is reliable and accurate, which can be used to determine the contents of loganin and paeoniflorin in Enriched Liuwei Dihuang pills.
