The content of vitamin C in 17 kinds of vegetables and fruits was analyzed by two different high-performance liquid chromatographic (HPLC) methods, one with electrochemical detection (HPLC-ECD), and the other with visible absorption detection (hydrazine/HPLC-VIS). The data and usability were compared between these two methods. The value for total vitamin C (ascorbic acid+dehydroascorbic acid) by HPLC-ECD was comparable to that by hydrazine/HPLC-VIS, and significant correlation was obtained (r=0.984, p<0.01). When compared to the hydrazine/HPLC-VIS method, HPLC-ECD required fewer steps for the analysis and a shorter analytical time, gave a higher specificity for ascorbic acid, and could be applied for the analysis of both ascorbic acid and dehydroascorbic acid. These results show the superiority of the HPLC-ECD method for a vitamin C analysis of vegetables and fruits.
