摘要： The alpha-lipoyl group-containing ascorbic acid derivative is provided to increase the stability of alpha-lipoic acid and ascorbic acid by binding two or more molecules of alpha-lipoic acid to ascorbic acid. The alpha-lipoyl group-containing ascorbic acid derivative having improved stability is represented by the chemical formula(1), wherein 2 or 3 of R1 to R4 is alpha-lipoyl group, and the remaining radical is hydrogen, and is selected from L-5,6-di-alpha-lipoyl-ascorbic acid, L-2,3-di-alpha-lipoyl-ascorbic acid and L-2,6-di-alpha-lipoyl-ascorbic acid. A method for preparing the alpha-lipoyl group-containing ascorbic acid represented by the chemical formula(1) comprises the steps of: (a) reacting the compound represented by the chemical formula(2) with the compound represented by the chemical formula(3), and (b) deprotecting the reaction product of step (a).
