摘要 目的:建立注射用丹酚酸A的HPLC含量测定方法。方法:采用高效液相色谱法,使用德国MN-C18(250 mm×4.6 mm,5μm)色谱柱,以乙腈-0.2%乙酸水溶液为流动相进行梯度洗脱,流速1.0 mL.min-1,检测波长286 nm。结果:丹酚酸A线性范围为10.93~218.60μg.mL-1(r=0.999 9),高、中、低3种不同浓度的回收率分别为99.5%,99.4%和99.3%。结论:本法精密度好,结果准确、可靠、灵敏,可用于注射用丹酚酸A的含量测定。 Objective: To develop a method for the determination of content of salvianolic acid A. Meth- ods: Analysis was carried out on a MN-Cls column (250 mm x 4.6 mm, 5 μm). The mobile phase was acetonitrile and water containing 0.2% acetic acid in gradient elution. The flow rate was 1.0 mL. min-1, and the detection wavelength was set at 286 nm. Results: The calibration curve of salvianolic acid A was linear in the range of 10.93-218.60 μg mL-l(r = 0. 999 9), and the average recoveries of its high, middle and low concentrations were 99.5% , 99.4% and 99.3% , respectively. Conclusion: The established method is accurate, credible and sensitive, and can be used for controlling the quality of salvianolic acid A for injection.
