A sensitive incision of puerarin on the cathodic branch of dE/dt-E curve was observed in 0.1 mol/L NaOH. The incision potential was -0.95 V (vs. SCE). The peak height on the second order differential simple oscillogram was proportional to the concentration of puerarin over 2.5×10 -6~3.5×10 -5 mol/L. The detection limit and the relative coefficient of the calibration curve were 1×10 -6 mol/L and 0.9985,respectively. The recoveries of puerarin in (Wild) Ohwi and Xin Ke Shu tablet were 100.2% and 96.9%,...

A sensitive incision of puerarin on the cathodic branch of dE/dt-E curve was observed in 0.1 mol/L NaOH. The incision potential was -0.95 V (vs. SCE). The peak height on the second order differential simple oscillogram was proportional to the concentration of puerarin over 2.5×10 -6~3.5×10 -5 mol/L.

The recoveries of puerarin in (Wild) Ohwi and Xin Ke Shu tablet were 100.2% and 96.9%, respectively. Compared with other methods, simple oscillographic voltammetry with second order differential was a convenient method due to its cheap equipment and rapid measurement and no need for O 2-eliminated.
