Title: Determination of paeoniflorin in Guishao capsules by HPLC
Abstract: Objective:To establish a HPLC method for determination of Paeoniflorin in guishao capsules. Methods:The HPLC method was used C18 column(250 mm×4.6 mm,5 μm).The mobile phase was methanol-water(25∶75).The detection wavelength was 230 nm.The flow rate was 1ml/min. Results: The calibration curve was linear in the range of 0.41~4.08 μg.The average recovery was 98.9% (RSD=0.6%). Conclusion:The method is sensitive, specific and repeatable.
