通过别洛索夫-扎鲍京斯基(B-Z)振荡反应研究不同产地中药紫菀鉴别的鉴别,将紫菀粉末加入H2SO4-Ce(SO4)2-CH2(COOH)2-KBrO3中,干扰化学振荡体系,用电化学工作站记录数据,并对温度、紫菀用量等反应条件进行了考察,确定体系的最佳实验条件为12 mL(3.0 mol/L)H2SO4溶液、3 mL(0.1 mol/L)Ce(SO4)2溶液、6 mL(1.0 mol/L)CH2(COOH)2和3 mL(0.2 mol/L)KBrO3溶液,温度310 K、加入0.4 g紫菀粉末,获得了不同产地紫菀的电化学指纹图谱。通过对不同产地中药材紫菀电化学指纹图谱的研究,发现不同产地的紫菀的指纹图谱主要参数有较大区别。该方法简便、准确、可靠,可方便的用于不同产地紫菀的鉴别。
Through the reaction of Belozov-Zabokensky (BZ) oscillation to identify differential identification of Aster in Chinese traditional medicine, Aster powder was added into H2SO4-Ce (SO4) 2-CH2 (COOH) 2-KBrO3 to disturb the chemical oscillation system , The electrochemical workstation was used to record the data and the reaction conditions such as temperature and the amount of aster were investigated. The optimum conditions of the system were 12 mL (3.0 mol / L) H2SO4, 3 mL (0.1 mol / L) Ce SO 4) 2 solution, 6 mL (1.0 mol / L) CH2 (COOH) 2 solution and 3 mL (0.2 mol / L) KBrO3 solution at 310 K were used to obtain the electrochemical fingerprint of Aster . Through the research on the electrochemical fingerprints of Aster in different producing areas, the main parameters of the fingerprints of Aster were found to be greatly different. The method is simple, accurate, reliable and convenient for the identification of Aster in different areas.
