Abstract: | The paper presents an approach to determine Paeoniflorin content in Shisan Taibao Pill using HPLC. In the study, Paeoniflorin was assayed on a Phenomenex GEMINI C18 (5μm, 4.6mm×250mm)column, with the mobile phase composed of Acetonitrile-0.1% phosphoric acid solution (17:83) at a flow rate of 1.0 mL·min^-1. The determination wavelength was set at 270 nm. The linear calibration curves were ranged between 0.0255-0.5110μg (r=-0.9995)for Paeoniflorin. The averages recovery (n=6) of Paeoniflorin was 97.98% (RSD=1.50%). Results show that the method is simple, reliable, accurate, and repeatable, desirable for the quality control of Shisan Taibao Pill. |
