ABSTRACT
Objective To establish a high performance liquid chromatography (HPLC) method for the determination of baicalin and naringin inQinbei mixture.Methods The HPLC system consisted of the Fortis-C18(4.6 mm × 250 mm, 5μm) column, and the mobile phase consisted of MeOH0.4% H3PO4 (4258), and the flow rate was 1.0 ml/min, and the UV detector was set at 280 nm, and the column temperature was 30℃.Results The linear response range of baicalin was 0.062-0.930μg. The linear response range of naringin was 0.033-0.492μg. The average recovery of baicalin was 98.11% (RSD=1.62%). The average recovery of naringin was 96.78% (RSD=1.74%).Conclusions The method is simple, rapid, accurate and repeatable. It can be applied in determination of baicalin and naringin inQinbei mixture.
