ABSTRACT:
Disclosed is an industrial-scale preparation of a high 2-O-.alpha.-D-glucopyranosyl-L-ascorbic acid content product with an improved purity, the preparation comprising subjecting a solution containing 2-O-.alpha.-D-glucopyranosyl-L-ascorbic acid and a saccharide derivative of L-ascorbic acid exhibiting a direct reducing activity to an oxidation treatment, subjecting the resultant mixture ti column chromatography using a strongly-acidic cation exchange resin, and recoverying the resultant high 2-O-.alpha.-D-glucopyranosyl-L-ascorbic acid content fraction. Thus, the preparatiobn has a great significance in the industrial field.
