中文摘要：

研究了抗癌药物冬凌草甲素在悬汞电极上的电化学行为。在NaAc-NaOH（pH7．8）的缓冲溶液中，冬凌苹甲素有一受吸附控制的还原峰，峰电位为-1．150V，峰电流与冬凌草甲素浓度在7．25×10^-7～1．01×10^-6mol／L范围内有良好的线性关系，检出限为1．45×10^-7mol／L（S／N=3）。对冬凌草片剂实际样品中冬凌草甲素含量测定，结果满意。

英文摘要：

The electrochemical behavior of idinonine （IDN） at the hanging mercury electrode has been investigated. In the acetic acid buffer solution （pH 7.8）, a adsorptlon-drlven reduce peak of idinonine is obtained with the peak potentials of -1. 150 V（vs. SCE）. The peak currents have a linear relationship with IDN concentrations in the range of 7.25 ×10^-7-1. 01×10^-6mol/L with the detection limit of 1.45 ×10^-7 mol/L. Based on this method, the idinonine content in rabdosia rubescens tablet was determined with satisfactory. Furthermore, the electrode process is also discussed simply.
