目的建立消渴灵胶囊中葛根素的含量测定方法。方法 HPLC法,KROM-C18柱,甲醇-水(26:74)为流动相,检测波长250 nm。结果此方法线性关系良好(r=0.9999),平均回收率为98.8%,RSD为0.85%(n=6)。结论方法简便,准确,可用于消渴灵胶囊的质量控制。
Objective To establish a method for the determination of puerarin in Xiaokeling capsule. Methods The HPLC method, KROM-C18 column and methanol-water (26:74) were used as the mobile phase. The detection wavelength was 250 nm. Results The linearity of this method was good (r = 0.9999). The average recovery was 98.8% and the RSD was 0.85% (n = 6). Conclusion The method is simple and accurate and can be used for the quality control of Xiaokeling capsules.
