摘要
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／LNaAc－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 (Vs,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。 japonica L. and rutin products can be directly determined without being separated previously. This method is simple,rapid and accurate.
