摘要：

L-ascorbic acid (AA) or Vitamin C is one of the most important water-soluble antioxidants and cellar redox-regulator. It is required widely in biological metabolism and is one of the most frequently taken vitamins to supplement inadequate dietary intake. Therefore, there has been wide demand in food and pharmaceutical industries and in nutritional assessment for the development of selective, simple, accurate and rapid technique to determine AA.
