Abstract: Objective:Study on the determination of macromolecular substances of Shengmai injection. Methods: Separation was performed on a G4000PWXL 7.8×300 mm,10 μm. The chromatographic column temperature is 35 ℃,the internal temperature is 35 ℃, and the mobile phase is 0.01% Na2SO4(Containing 0.02%NaN3) at a flow rate of 0.6 mL·min-1.Results:The products of 8 companies all have the 2 700(Dextran D1)-64 650(Dextran D6) polysaccharide macromolecules, and the data of each batch in each manufacturer is relatively parallel. Conclusion: This method has a good repeatability and can be used to determine the relative molecular weight and distribution of macromolecules in Shengmai injection. The results can be used to improve the quality standard of Shengmai injection.
