Abstract

5-O-.alpha.-D-Glucopyranosyl-L-ascorbic acid is a novel derivative of L-ascorbic acid which has a direct reducing activity and a satisfiable stability, as well as being readily hydrolyzed in vivo to form L-ascorbic acid. The 5-O-.alpha.-D-glucopyranosyl-L-ascorbic acid is prepared by allowing a saccharide-transferring enzyme together with or without .alpha.-glucosidase to a solution containing an a-glucosyl saccharide and L-ascorbic acid, and suitably used in food products, agents of anti-susceptive diseases and cosmetics containing thereof.
