摘要

Malvidin-3-glucoside has been labeled by enzymatic synthesis in a single-step experiment. Catechol-O-methyl transferase catalyzed the B-ring methylation of petunidin-3-glucoside, and S-Adenosyl-L-[methyl-(3)H] methionine was the methyl donor. Solid phase extraction and preparative high-performance liquid chromatography were necessary to separate [3'-O-methyl-(3)H]malvidin-3-glucoside from an isomer and the starting material. The specific activity was 2.2 Ci mmol(-1), and the yield of incorporation was 1.1%. A possible application of the labeled material is the study of anthocyanin reactions in complex mixtures such as red wine where products are difficult to isolate and analyze.
