目的建立液相色谱法测定唐福康胶囊中罗格列酮含量的方法。方法选用C18色谱柱,以0.01 mol/L醋酸胺(用冰醋酸调节pH值至3.5)-乙腈(45:55)为流动相,UV检测波长为230 nm。结果本方法的回收率为99.31%,RSD=0.9%(n=6)。结论该方法简便,准确,重现性好。
Objective To establish a method for the determination of rosiglitazone in Tangfukang capsule by liquid chromatography. Methods C18 column was used with the mobile phase of 0.01 mol / L ammonium acetate (adjusted to pH 3.5 with glacial acetic acid) - acetonitrile (45:55). The UV detection wavelength was 230 nm. Results The recovery of this method was 99.31% with RSD = 0.9% (n = 6). Conclusion The method is simple, accurate and reproducible.
