Abstract
目的:建立RP-HPLC法同时测定三黄片中黄芩苷、小檗碱、大黄素和大黄酚的含量。方法:色谱柱为KromasilKR100-5 C18柱(250 mm×4.6 mm,5μm);流动相:乙腈(A)∶3%乙酸水溶液(B);梯度洗脱程序:A(%)∶B(%)=23∶77(0~9 min),流速1 mL/min,A(%)∶B(%)=28∶72(10~21 min),流速0.7 mL/min,A(%)∶B(%)=66∶34(22~35 min),流速1 mL/min;检测波长270 nm;柱温35℃。结果:四组分均达到基线分离,各组分的平均回收率为97.00%~102.55%,方法的精密度、稳定性和重现性良好。结论:本方法快速、可靠、简便,具有应用价值。
