A method was developed for extracting, identifying, and quantifying diphenylamine (DPA) derivatives in the peel of DPA-treated apples using gradient reversed-phase liquid chromatography with ultraviolet-visible absorption and atmospheric pressure chemical ionization detection (LC-UV-vis-APCI-MS). Compounds routinely analyzed using this method included hydroxylated, nitrosated, nitrated, and methoxylated diphenylamine derivatives. Analysis of peel treated with 0-8 g L(-1) DPA showed that peel DPA content was a limiting factor in derivative production and that recovery of most compounds over this range was linear.
开发了一种方法，用于使用梯度反相液相色谱结合紫外可见吸收和大气压化学电离检测（LC-UV-vis-APCI-MS）来提取、鉴定和定量经二苯胺（DPA）处理的苹果果皮中的二苯胺衍生物。使用该方法常规分析的化合物包括羟基化、亚硝化、硝化和甲氧基化二苯胺衍生物。对用0-8 g L(-1) DPA处理的果皮进行分析表明，果皮DPA含量是衍生物产生的限制因素，并且在此范围内大多数化合物的回收率呈线性。
