摘要: 研究了利用薄层扫描法测定 L 抗坏血酸棕榈酸酯 ( L AP)的可行性 ,优选了测定条件 ,建立了测定其含量的薄层扫描法。本法检测范围为 2 5～ 2 0 μg,相对标准偏差为 1 34 % ,回收率为 98 4 %～ 1 0 1 8%。Abstract: A new method is presented for determination of ascorbyl palmitate with thin layer chromatography.The method is based on the reaction of 2, 6 Dichlorphenolindophnol Natriumsalz Dihydrate with ascorbyl palmitate.Optimum experimental conditions have been established.The determination range of 2.5～20μg, the recovery of 98.4%～101.8%, and the variation coefficient of 1.34% are given.
