Study on the electrochemical fingerprint of Chuzhou chrysanthemum morifolium

To evaluate the global property of Chuzhou chrysanthemum morifolium and discriminate the species of chrysanthemum morifolium,electrochemical fingerprint of Chuzhou chrysanthemum morifolium was analyzed and discussed inBrO_3~- - Ce~(4+)- H~+- malonic acidoscillation system using malonic acid as main dissipation substance.The results showed:The optimum conditions of drawing electrochemical fingerprint of Chuzhou chrysanthemum morifolium were obtained as that the temperature of oscillation system was 25℃,the dosage of Chuzhou chrysanthemum morifolium was 1.0g which particle size was 60 mesh.The apparent activation energies of the oscillatory reactions of Chuzhou chrysanthemum morifolium during induction period and oscillation period was respectively 69.07kJ ? mol~(-1) and 56.57kJ ? mol~(-1).Under the same condition of drawing electrochemical fingerprint, Chuzhou chrysanthemum morifolium,Hangbai chrysanthemum morifolium and Huangshan chrysanthemum morifolium had different information.These characteristic data were beneficial to discriminate the species of chrysanthemum morifolium.Thus,electrochemical fingerprint was a better way to evaluate the global property of Chuzhou chrysanthemum morifolium and discriminate the species of chrysanthemum morifolium.
