摘要：

Decolourization of anthocyanins by sulfur dioxide is investigated through the reaction between sodium bisulfite and malvidin 3-O-glucoside. The structural elucidation of the C-4 sulfonate adducts is established by H-1, C-13 and S-33 NMR spectroscopies. (C) 1998 Elsevier Science Ltd. All rights reserved.
