ABSTRACT
Objective To establish a content determination method for paeoniflorin in qisheng capsule. Methods The quantitative analysis of paeoniflorin in qisheng Capsule was carried out by high-performance liquid chromatography ( HPLC) . The chromatographic separation was achieved by using a Kromasil C18 chromatographic column (4. 6 mm×250 mm,5 μm) with a mobile phase consisting of methanol,water (1585) at a flow rate of 1. 0 mL·min-1 and 230 nm detection wavelength. Results The linear range was 2. 5-12. 5 μg·mL-1( r =0. 999 9). The average recovery and RSD of the method were 99. 97%and 0. 94%. Conclusion The method is accurate,specific,reproducible,which can effectively be used in quality control of paeoniflorin in qisheng capsule.
