电化学指纹图谱法鉴别红花

Identification of Safflower by Nonlinear Chemical Fingerprinting

目的:利用中药红花作为电化学反应底物,建立一种鉴别中药红花真伪的方法。方法:采用H+-Mn2+-CH3COCH3-Br O3为振荡体系,以一定量的中药红花为反应底物,反应温度控制为310 K,搅拌速度为500 r·min-1,获得电化学指纹图谱。结果:中药红花的电化学指纹图谱重复性良好,红花及其伪品的电化学指纹图谱振荡参数差异明显。结论:可以用已建立的电化学指纹图谱法鉴别红花的真伪。

Objective： The establishment of a method to identify the authenticity of Chinese safflower, the use of safflower as the electrochemical reaction substrate. Method： In a glass reactor with appropriate amount of Chinese herbal medicine as the substtate of reaction, the H＋-Mn2＋-CH3COCHa-BrO3 for oscillation system. Temperature kept at 310 K and the stirring speed was 500 r.min^-1. Getting the non-linear electrochemical fingerprint. Result： Electrochemical fingerprint of Chinese safflower repeatability is good, and there are significant differences in the electrochemical fingerprint of safflower and its counterfeit products. Conclusion： This method can be used to identify safflower.
