摘要
目的:建立反相高效液相色谱法同时测定冠心宁冻干粉针剂中9个酚性成分(丹参素、原儿茶酸、原儿茶醛、绿原酸、咖啡酸、阿魏酸、异阿魏酸、迷迭香酸、丹酚酸B)的含量。方法:采用Luna C18色谱柱(250 mm×4.6 mm,5μm),以乙腈-磷酸水溶液为流动相系统进行梯度洗脱,检测波长280 nm,柱温35℃。结果:待测组分在各自浓度范围内与峰面积呈良好线性关系,R2均大于0.99,平均回收率(n=9)分别在96.3%~104.3%之间。结论:测定方法准确、灵敏,重复性好,为全面评价冠心宁冻干粉针剂质量提供了可靠方法。
Objective:An effective,accurate and reliable method for the determination of nine phenolic components(danshensu,protocatechuic acid,protocatechuic aldehyde,chlorogenic acid,caffeic acid,ferulic acid,isoferulic acid,rosmarinic acid,salvianolic acid B) in Chinese medicine Guanxinning lyophilized powder for injection was developed.Methods:The separation,using reversed phase high-performance liquid chromatography(RP-HPLC),was performed on a Luna C18 column(250 mm×4.6 mm with 5 μm particle size) with a gradient elution programme when the wavelength was 280 nm and the column temperature was 35 ℃.Results:Excellent linear behaviors over the investigated concentration ranges were observed with the value of R2 higher than 0.99 for all the analytes.The recoveries,measured at three concentration levels,varied from 96.3% to 104.3%.Conclusion:The method is accurate,reliable and effective for the simultaneous determination of nine phenolic components in Guanxinning lyophilized powder for injection.
