摘 要 ：应用高效液相色谱法测定了大黄及其炮制品中总大黄素的含量。以甲醇-水(80:20)并用磷酸调节pH为3时,能使待测组分达到较理想的分离度。实验表明,该法的重现性、回收率均较好,具有快速、准确、灵敏的特点。

Abstract:This paper deals wich the effect of processing on Rheum palmatum. A HPLC methed for the determination ofrhein in the drug procossed five different ways has been established The method is simple, specific and accurate. Therecovery is 98. 52% and relative standard deviation.
