摘要
采用HPLC测定清喉咽颗粒剂中黄芩苷的含量,以甲醇—02%磷酸溶液(70∶30)为流动相,检测波长为317nm,黄芩苷在0~04920μg范围内线性关系良好,r=0997。平均回收率为1009%,RSD=099%(n=5)。方法简便,准确。
This assay presents the determination of Baicalin in Qinghouyan granules.Baicalin is separated by Alltima C 18 column(4 6 mm×250 mm)and detected at 317 nm.Mobile phase is methanol-0 2 % phosphoric acid solution(70∶30).The calibration curve is linear between 0~0 4920 μg with a correlation coefficient of 0 9997.The average recovery was 100 9 % with RDS of 0 99 %.The method is simple and quick with the high sensitivity.
