Abstract: Objective To establish methods for identification and quantification of Angelica sinensis and Ligusticum chuanxiong in Su′s Fracture Healing Capsule.Methods Su′s Fracture Healing Capsules were identified by TLC.A new HPLC method was developed to quantitatively analyze the total ferulic acid which was the sum of free ferulic acid and hydrolyzed components.A Thermo C18(250 mm×4.6 mm,5 μm)was used with acetonitrile-1% acetic acid(20∶80)as the mobile phase.The flow rate was 1.0 mL/min and the column temperature was at 25 ℃.The detective wavelength was set at 320 nm.Results Spots obtained from the test solutions had the same color as Angelica sinensis and Ligusticum chuanxiong reference substances and the blank solution had no interference.The linearity range of ferulic acid was 0.42—2.24 μg.The average recovery of ferulic acid was 99.26% with the RSD of 1.27%.Conclusion The method of identification and quantification were accurate,simple and reproducible.It can be used for the quality control of Su′s Fracture Healing Capsule.
