和厚朴酚在0．1mol/LNH3－NH4Cl缓冲溶液（pH9．4）中，用线性扫描伏安法得到两个还原峰P1和P2。峰电位分别为Ep1＝－0·23V和Ep2＝-1.18V（vs.Ag／AgCl）。用线性扫描与循环伏安法、脉冲极谱法和恒电位库仑法等手段研究体系的电化学行为及其反应机理。实验表明，P1和P2均为不可逆波。P1和P2的电子转移数均为2。和厚朴酚在汞电极上的吸附具有中性分子吸附的特征，吸附符合Frumkin吸附等温式，吸附系数β＝4．0×105mol/L，吸引因数α＝1．54，饱和吸附量гm=7．4×10-11mol·cm－2。P1的电子转移系数为0．80，非均相电极反应速率常数k1＝3．2×10-4cm／s。通过量化计算，证明P1是分子中酚羟基邻位上的碳碳双键的还原峰，P2是其对位上的碳碳双键的还原峰。
In the 0.1 mol / L NH3-NH4Cl buffer solution (pH9.4), two reduction peaks P1 and P2 were obtained by linear sweep voltammetry. The peak potentials were Ep1 = -0.23 V and Ep2 = -1.18 V (vs. Ag / AgCl), respectively. The electrochemical behavior and reaction mechanism of the system were studied by means of linear sweep and cyclic voltammetry, pulsed polarography and potentiostatic coulometry. Experiments show that P1 and P2 are irreversible waves. P1 and P2 electron transfer number of two. The adsorption of honokiol on mercury electrode was characterized by neutral molecular adsorption. The adsorption was in accordance with the Frumkin adsorption isotherm. The adsorption coefficient was 4.0 × 105mol / L, the attraction factor was α = 1.54, the adsorption capacity was гm = 7.4 × 10-11mol · cm-2. The electron transfer coefficient of P1 was 0.80, and the reaction rate constant k1 of the heterogeneous electrode was 3.2 × 10 -4 cm / s. Through quantitative calculation, it is proved that P1 is the reduction peak of the carbon-carbon double bond in the ortho-position of the phenolic hydroxyl group in the molecule, and P2 is the reduction peak of the carbon-carbon double bond in the para-position thereof.
