HPLC测定参姜锁阳益气片中淫羊藿苷的含量
摘要
目的:建立测定参姜锁阳益气片中淫羊藿苷含量的高效液相色谱方法。方法:采用美国Agilent zorbax extend-C18(4.6 mm×250 mm
5μm)柱
以甲醇-水-冰乙酸(54∶46∶1)为流动相
流速1.0 mL.min-1;在270 nm波长处检测
柱温30℃。结果:淫羊藿苷在4.0~18.0μg呈线性关系
r=0.999 6;平均加样回收率为99.63%
RSD为1.40%(n=6)。结论:该方法简便易行
结果准确、可靠
重复性好
可用于参姜锁阳益气片中的淫羊藿苷的含量测定。
Abstract
Objective:To establish a method for HPLC determination of icariin in Shenjiang Suoyang Yiqi tables.Method:The condition for HPLC was Agilent zorbax extend-C18(4.6 mm × 250 mm
5 μm)
agilent the detection wavelengths 270 nm.Result:The standard curve was liner in the range of 4.0-18.0 μg and the correlation coefficient was 0.999 6.The coverage recoverywas 99.63% with RSD 1.40%(n = 6).Conclusion:The method is simple
separating result
acuracy and reproducibility
can be used for the quality control of Shenjiang Suoyang Yiqi tables.
