摘要
采用循环伏安法研究隐丹参酮在电极上的电化学行为及建立差示脉冲伏安对其测定的新方法。在pH4．0乙酸盐缓冲液中，氧化峰电流与隐丹参酮浓度在3．0×10^-8～2．0×10^-7mol／L范围内呈良好的线性关系，检出限为2．0×10^-9mol／L。玻碳电极可有效消除样品中其它组分对隐丹参酮测定的干扰，已用于实际样品中隐丹参酮的直接测定。该方法灵敏度高、检测范围宽。
The electrochemical behavior of cryptotanshinone was investigated by cyclic vohammetry at a glassy carbon electrode. And differential pulse vohammetric method for the determination of cryptotanshinone was developed. In a pH 4.0 acetate buffer solution, the relationship between oxidation peak current and the concentration of cryptotanshinone was linear in the range of 3.0 × 10^-8 ～ 2.0 × 10^-7 mol/L. The detection limit was 2.0 × 10^-9 mol/L. The interference of other components in the preparation could be efficiently eliminated by the glassy carbon electrode. And this method can be used for the determination of Cryptotanshinone in real samples with satisfactory results.
