It has been found that ascorbic acid (AA) and dehydro-ascorbic acid (DHAA) can be derivatized to the compounds having a maximum absorption wavelength of 3OOnm under alkaline conditions, and that der¡vatizati on of DHAA is accelerated in the presence of a reducing agent such as sodium borohydride. This reaction has been applied to post-column derivatization in high performance liquid chromatography (HPLC) for the simultaneous determination of AA and DHAA, In this system, AA in the range of 1ng 2 µ g and DHAA in the range of 2ng 2 µ g have been determined simultaneously with good reproducibility, C. V 1.5% (n = 10).
