Abstract: Determination of saccharides in orange juice was studied by high performance liquid chromatography. Saccharides were extracted from samples with water by oscillation and isolated by solid phase extraction with Sep-Pak-C18 cartridge. Sucrose, glucose and fructose were separated on an Agilent Zorbax Carbohydrate column(4.6×250mm, 5μm), with 80% acetonitrile solution as mobile phase, around temperature 25±2℃. The relative standard deviations are 0.83%~1.71% and the recoveries are 96%~103%. This method can be applied to the determine saccharides components in orange juice.
