Keyword:  高效液相色谱法丹参素原儿茶醛丹参冠心Ⅱ号含量测定;
Abstract: 目的测定不同煎煮条件下丹参和冠心Ⅱ号中丹参素、原儿茶醛的含量.方法采用反相高效液相色谱法.Kromasil C18柱(250 mm×46 mm,5μm);流动相:乙腈-0.01 mo1/L磷酸二氢钾溶液(9:91),磷酸调至pH 2.8;检测波长:280 nm;流速:1.0 mL/min.结果丹参素在0.245~5.880 μg(r=0.9998)、原儿茶醛在0.011~0.504 μg(r=0.9996)范围内呈线性,丹参素和原儿茶醛最低检测浓度分别为9.8 ng/mL和2.1 ng/mL,回收率分别为97.81%(RSD=1.13%)和94.72%(RSD=1.18%).结论该方法可用于丹参及冠心Ⅱ号制剂的质量控制.
