高效液相色谱法测定千金保孕丸中黄芩苷的含量
摘要
目的:建立千金保孕丸中黄芩苷的含量测定方法。方法:采用Agilent Hypersil ODS(4.0 mm×250 mm
5μm)色谱柱
流动相为甲醇-0.4%磷酸(43:57)
流速为1 mL·min-1
检测波长为280 nm。结果:黄芩苷在(7.23
1
15.68)μg·mL-1范围内
具有良好的线性关系(r=0.9999)
平均回收率(n=6)为100.6%
RSD=0.58%。结论:本方法简单、准确
可用于千金保孕丸的质量控制。
Abstract
Objective:To develop an HPLC method for determination of baicalin in Qianjin Baoyun Pills.Methods:The chromatographic column was Agilent Hypersil ODS(4.0 mm×250 mm
5 μm).The mobile phase was methanol-0.4% phosphoric acid(43∶57).The flow rate was 1 mL·min
-1
and the detection wavelength was 280 nm.Results:The linear range of baicalin was within(7.23~115.68)μg·mL
-1
(r=(0.999 9))
the average recovery for baicalin was 100.6%
RSD was 0.58%.Conclusion:This method is simple
accurate and could be used for quality control of Qianjin Baoyun Pills.
