摘　　要：建立溶剂萃取-差示脉冲溶出伏安法测定橘皮中的邻苯基苯酚(OPP)的方法。为避免橘皮中大量抗坏血酸和香精油等物质的影响,采用甲苯萃取橘皮中的OPP,在优化实验条件下,运用差示脉冲溶出伏安法测定橘皮中OPP含量。结果表明,OPP氧化峰电流与其浓度在2.0×10-9～4.0×10-6 mol/L范围内呈良好的线性关系,检出限达到8.1×10-10mol/L,回收率为106.7%～112.2%。该法操作简单、快速、灵敏、准确。The solvent extraction-differential pulse stripping voltammetry method was developed to determine O-phenlyphenol（OPP） in orange peel.In order to avoid the influence of ascorbic acid and essential oil,OPP was extracted by toluene from orange peel.Under the optimal conditions,differential pulse stripping voltammetry was used to determine OPP in orange peel.The results demonstrated that the oxidative peak current of OPP was linearly correlated with the OPP concentrations in the range of 2.0×10^-9-4.0×10^-6 mol/L.The detection limit and recovery rate of this developed method were 8.1×10^-10 mol/L and 106.7%-112.2%,respectively.Therefore,this developed method is characteristics of simple operation,fast detection,high sensitivity and accuracy.
