Abstract

Several flavonols of therapeutic interest on account of their vascular properties have been studied. They were all derived from the o-diphenol quercetol. Their electrochemical oxidation at a rotating solid electrode has been examined, and the choice of solvent and pH is discussed. Results obtained by d.c. and pulse polarography are presented. A relation between their structure and electrochemical behaviour has been established. Application to drug analysis is proposed, giving identification, determination and purity assay simultaneously. There is a linear response over the range 5 x 10(-6)-10(-4)M, a sufficient range for analysis of pharmaceuticals.
