The oxidation mechanism of synephrine was also investigated;(2) The electrochemical behavior of twelve flavonoids (quercetin, morin, fisetin, luteolin, isorhamnetin, myricetin, hyperoside, quercitrin, puerarin, farrerol, naringenin and hesperidin) was investigated. The method for the determination of flavonoids was developed by using different pulse voltammetry, and the detection limit was in the range of 10-7~10-9 mol/L. This method has been successfully employed to determine the total amount of flavonoids in pericarpium citri reticulatae and quercetin in the spiked human blood plasma samples.
