Study on detection methods for ascorbic acid in medicine and food

Ascorbic acid (AA) is an essential nutrient for health maintenance. It plays an important role in many biological processes, such as collagen formation, amino acid metabolism, ion absorption and so on. The deficiency of AA will lead to the symptoms of scurvy and gingival bleeding, while excessive intake of AA will result in diarrhea, hyperacidity and kidney calculi. Therefore, the rapid, sensitive, and selective detection of AA level is significant for food and pharmaceutical analysis, clinical diagnosis applications. In this article the studies of detection methods for AA in recent years are reviewed.
