摘要：

An analytical procedure based on the proportionate decrease in the color intensity of U-VI-4-(2-pyridylazo)resorcinol complex with the increasing amount of vitamin C is described. The complex shows lambda(max) at 530 nm. Beer's law holds well in the range 2-16 mug ml(-1). The applicability of the method is, tested by analyzing pure vitamin C solutions and multivitamin pharmaceuticals.
