| Abstract: | Objective：To establish an RP-HPLC method for quantitative determination of Total Flavonoid in Yinxingye Soft Capsules.Methods：The analytical column was Agilent C18（4.6 mm× 250 mm,5 μm） column.The mobile phase was composed of methanol and water（with phosphoric acid pH=2） at a flow rate of 1.0 ml/min.The wavelength of UV detector was 360 nm and column temperature was 30℃.Results：The linear ranges of Quercetin,Kaempferol and Isorhamnetin were 0.050-0.400,0.005-0.040,0.005-0.040 μg,respectively.The contents of Total Flavonoid in three batches of samples were 1 Capsule 6.466,6.455,6.838 mg.Conclusion：This method is sensitive,repeatable and suitable to determine the content of Total Flavonoid in Yinxingye Soft Capsules. |
