丹皮酚的电化学性质研究及其应用
Study on the Voltmeter Behavior and Its’ Applying in Paeonol Determined
【摘要】 目的建立丹皮酚电化学检测方法,并应用于丹皮中丹皮酚含量的测定。方法循环伏安(CV)、差分脉冲(DPV)。结果在0.1 mol/L的NaOH-NaH2PO4(pH=11)底液中1、00 mv/s的扫描速度下丹皮酚在铂电极上有一灵敏的氧化峰,峰电流与其浓度在5.0×10-6~1×10-3mol/L的范围内呈良好的线性关系,其线性回归方程为:A=0.23-4 082.64×C(r=0.998 4),检出限为1×10-6mol/L。结论该方法准确可靠,操作简便、快速,重现性好,可用于在线和野外检测。
【Abstract】 Objective To establish the electric chemistry analysis method for determining content of paeonol from Paeonia suffruticosa. Methods Cyclic Voltmeter and Differential Pulse Voltmeter methods were used.Results In 0.1mol·L-1 NaOH-Na H2PO4 buffer solution(pH=11),sensitive oxidization peak of paeonol was obtained.The peak current showed a good linearity within the range of 5.0×10-6~1.0×10-3 mol·L -1 with the detection limit of 1.0×10-6mol·L-1 of paeonol,and the regression equation was A= 0.23-408 2.64C(r=0.998 4).Conclusion This method was accurate,dependable and reproducible,it may be used to determine content of paeonol on line and in the field measuring.
