摘要:

基于曲克芦丁对Belousov-Zhabotinskii振荡体系的扰动, 建立了一种测定曲克芦丁的新方法. 在优化条件下, 振幅改变量ΔE与曲克芦丁的浓度在0.808~40.4 μmol/L范围内呈现良好的线性关系, 检出限为2.14×10-7 mol/L(S/N=3). 对曲克芦丁注射液中的曲克芦丁进行了分析测定, 回收率在98.8%~101%之间, 测定结果与紫外法无显著性差异. 采用循环伏安法和紫外分光光度法对可能的扰动机理进行了探讨.

Abstract:

A new method for the determination of troxerutin was developed based on the disturbance of troxerutin to Belousov-Zhabotinskii oscillation system. Under optimal conditions, the variation of ΔE had a linear relationship with troxerutin concentration in the range of 0.808—40.4 μmol/L, with detection limit of 2.14×10-7 mol/L(S/N=3). The established method was used to determination of troxerutin in injection, and the recovery was 98.8%—101%. The results showed that the data obtained by this method and the ones by UV method had no significant difference. The possible mechanism was studied using cyclic voltammetry and UV spectrophotometry.
