The quantitative determination of danshensu in danshen dripping pill
Abstract:Objective:To establish a HPLC method for the quickly determination of Danshensu content in Compound Danshen Dripping Pill. Methods:The analysis was carried on a Hypersil C18 ( 4.6 mm ×250 mm , 5 μm ) column. The mobile phase was methanol-water-acetic acid (20:80:0.5)and the detection wavelength was 281nm. Results: Sodium Danshensu showed a good linearity in the range of 0.0298~0.2681mg/mL, r=0. 9992. The average recovery was 101.28%, and RSD was0.471%(n=5). Conclusion:This method is effective,quick and can be used for the quality control of Danshensu in Compound Danshen Dripping Pill.
