目的:建立千斤脑康宁胶囊中丹酚酸B的含量测定方法。方法:采用高效液相色谱法,kromasilC18柱(4.6 mm×250 mm,5μm),甲醇-乙腈-1%甲酸溶液(24∶10∶66)流动相,286 nm检测波长,柱温室温。结果:丹酚酸B在0.24~4.04μg,峰面积与其浓度呈良好线性关系(r=0.999 8),平均回收率97.5%,RSD 1.27%(n=6)。结论:该方法简便、准确、重复性好,可作为该制剂含量测定方法。 Objective: To establish a method for the determination of salvianolic acid B in jin jin er ning capsule. Methods: The mobile phase of kromasil C18 column (4.6 mm × 250 mm, 5 μm) and methanol-acetonitrile-1% formic acid solution (24:10:66) were used for detection of the wavelength at 286 nm. Results: There was a good linear relationship between the concentration of salvianolic acid B and its concentration (r = 0.999 8). The average recovery was 97.5% and the RSD was 1.27% (n = 6). Conclusion: The method is simple, accurate and reproducible, and can be used as a method for determination of the content of the preparation.
