Abstract： 目的:建立冠心Ⅱ号中丹参素、原儿茶醛、芍药苷和阿魏酸同时测定的高效液相色谱法. 方法:固定相,ZORBAX Extend-C18反相柱(150×4.6 mm 5 μm). 流动相,0 min,A(10 mL/L乙酸甲醇溶液)∶B(10 mL/L乙酸水溶液)=15∶85;25 min,A∶B=40∶60,线性梯度洗脱. 流速,1.0 mL/min;柱温,室温. 检测波长,丹参素和原儿茶醛280 nm;芍药苷230 nm;阿魏酸321 nm. 结果:丹参素、原儿茶醛、芍药苷和阿魏酸的线性范围分别是25.0～600.0, 0.8～25.6, 80.0～1280.0和10.0～160.0 ng,相关系数r分别是0.9993, 0.9999, 0.9995和0.9994,平均加样回收率(n=5)分别是102.19%(RSD=0.51%), 100.54%(RSD=4.67%), 99.99%(RSD=5.02%)和98.6%(RSD=6.72%). 结论:方法简便,结果准确,可用于冠心Ⅱ号的质量控制和治疗药物监测.
