摘要
目的建立胃康胶囊中芍药苷的含量测定方法。方法以Ultimate TM XB—C18(4.6mm×250mm,5 um)为分析柱,异丙醇-甲醇-醋酸-水(2:25:2:71)为流动相;流速:1.0ml·min-1;检测波长:230nm;进样量10ul。结果芍药苷对照品在10.80~97.20ug.ml-1范围内,浓度与峰面积呈良好的线性关系Y=4.74×10 3X+2.44×10 3,r=0.9999,平均回收率为99.2%,RSD=0.5%(n=9)。结论本法简便,准确,专属性强,可以作为该制剂的质量控制方法。
Objective To establish a method for determination Content of paeoniflorin in weikang capsule by HPLC. Methods The HPLC was conducted on a UltimateTM XB-CI8 with isopropanol - methanol- acetate-water( 2:25:2:71 ) as mobile phase, flow rate 1.0 ml. min-1; detected at 230nm; injection volume 10 ul. Results The calibration crave of paeoniflorin was linear with 10.80 - 97.20 u. g. mL-1, linear relationship Y=4.74 × 10 3X+2.44 × 10 3, (r=0.9999),The average recovery of paeoniflorin was 99.2%, RSD = 0.5% (n=9). Conclusion The method is simple, accurate and suitable for the determination of weikang capsule.
