ABSTRACT
To establish a method for the simultaneous determination of 9 components, namely gardenoside, paeoniflorin, forsythoside A, baicalin, forsythin, glycyrrhizic acid, rhein, honokiol, and magnolol in Xiao'er Chiqiao Qingre granules(XECQ Gra). Ultra performance liquid chromatography (UPLC) was used on an Acquity UPLC HSS T3 C₁₈ column (2.1 mm×100 mm, 1.8 μm) with 0.1% phosphoric acid acetonitrile (A)-0.1% phosphoric acid solution (B) as mobile phase for gradient elution. The flow rate was 0.3 mL·min⁻¹ ; the column temperature was set at 30 °C, and the determination wavelength was set at 220 nm. All the 9 compounds were well separated, and showed good linear relationship within their concentrations (r>=0.999). The average recoveries were between 95.84%-101.4% and the RSD values were all less than 3.0%. The method is simple, reliable, and accurate, and could be used for the quality control of XECQ Gra.
