HPLC测定豨莶风湿片中粉防己碱含量
摘要
目的:建立HPLC测定豨莶风湿片中粉防己碱含量。方法:采用Diamonsil C18色谱柱
以甲醇-0.3%二乙胺(75∶25)为流动相
检测波长280nm。结果:粉防己碱在0.191 25~1.53μg线性关系良好
r=0.999 8
平均回收率为97.4%(n=5)
RSD 1.3%。结论:本法简便、准确、重复性好
可用于豨莶风湿片中粉防己碱的含量测定。
Abstract
Objective: To establish HPLC for determining the content of tetrandrine in Xixian Fengshi tablet.Method:An HPLC method was developed.The chromatographic conditions were as follow: Diamonsil C18 column and methanol-0.3% diethylamine(75∶25) as mobile phase
detection wavelength at 280 nm.Result:The recovery range of tetrandrine was 0.191 25-1.53 μg
r = 0.999 8.The average recovery rate was 97.4% and RSD was 1.3%.Conclusion: The method is simple and accurate
with good repeatability
and can be used for determination of tetrandrine in Xixian Fengshi tablet.
