摘要：

The reaction of L-debydroascorbic acid (DHA) with primary aliphatic amines including N-alpha-acetyllysine was examined by HPLC A new aminoreductone, 2-deoxy-2-(propylamino)ascorbic acid (1) was isolated and the structure elucidated by spectroscopic data. Furthermore oxalic acid mono-(2) and diamides (3) were identified as important degradation products of DHA under Maillard conditions, 3-Deoxy-3-(alkylamino)ascorbic acids (4), typical condensation products of L-ascorbic acid and amines, were also detected in the reaction mixtures of DHA. All produces are formed under oxidative and nonoxidative conditions from DHA.
