Abstract

In solution of 0.1mol/L Tris-HCl(pH=8.3),a sensitive reduction peak of rutin was obtained by liner sweep polarography.The peak potential was-1.10V(vs.Ag/AgCl).The peak current was proportional to the concentration of rutin over the range of 7×10-7~9.8×10-6mol/L.This method has been applied to the determination of the flavonoid in G.Uralensis.The results showed that the reduction process was irreversible with adsorption that studied by linear sweep and cyclic voltammetry.
