目的:研究中药木通的电化学指纹图谱,考察反应温度、药材加入量等影响因素,并用电化学指纹图谱对不同产地中药木通进行鉴别。方法:采用B-Z震荡技术,将木通粉末加入以丙二酸为耗散物的BrO^(3-)+H^++Ce^(4+)+丙二酸振荡体系中,用电化学工作站记录数据,用Origin软件绘制电位(E)随时间(t)变化的曲线,计算数据,分析图谱。结果:考察了不同条件对B-Z振荡图谱的影响,获得了不同产地木通的电化学指纹图谱,并对其电化学指纹图谱进行了探讨。确定最佳实验条件为:温度310 K、转速400 r·min^(-1)、药材加入量为0.200 0 g。结论:电化学指纹图谱简便、快速、直观,可方便地用于不同产地木通的区分和鉴别。

Objective： To identify Akebia by using electrochemical fingerprints. Methods： The B-Z chemical oscillating method was applied in the study, oscillating chemical reaction was studied in the system of BrO3- ＋ H ＋ ＋ Ce4 ＋ ＋ CH3 COCH3. Akebia powder was added to the chemical oscillation system, electricity chemistry workstation record data, E-t curve drawing with Origin software, data calculation, analysis of map. Results： The influence of different conditions on B-Z oscillation pattern was examined, the different regions＇electrochemical fingerprints were obtained. The optimum conditions were as follows： 310 K the temperature, 400 r·min^-1 the speed and adding 0. 200 0 g of Akebia powder. Conclusion： The electrochemical fingerprints can be used for identifying the Akebia. The established method is fast, convenient and it has the advantage of convenience, fast and intuitive.
