利用单扫示波极谱法测定了槐米和芦丁制剂(芦丁片、复方芦丁片)中芦丁的含量。芦丁在0．1mol／L NaAc－HAc缓冲液(pH=3．5)中于-1．38V(vs．SCE)左右产生灵敏的还原波。主峰与其浓度在1．0×10-8～9．0×10-4mol／L范围内呈线性关系，检测限为1．5×10-10mol／L。考察了人体中常见物质的影响，探讨了电极反应机理。对样品可不经分离，直接测定，方法简便，准确可靠。

Contents of rutin in Sophora japonica L. and rutin products (rutin tablets and compound rutin tablets) were determined by single-sweep oscillopolarography. In 0. 1 mol/L NaAc-HAc (pH=3. 5 ) buffer solution,rutin showed a well defined cathodic peak,with a peak potential of 1. 38V (V-SCE). The peak height is linearly proportional to its concentration in the range of 1.0 × 10^-8～9.0 × 10^-4mol/L. The detection limit is 1.5 × 10^-10mol/L. The contents of rutin in S.japoreica L. and rutin products can be directly determined without being separated previously. This method is simple,rapid and accurate.
