[Dihydroquercetin polymerization using laccase immobilized into an ionic liquid].
It was shown that the laccase (LC) included into hydrophobic ionic liquid (IL) can be reused for the biotransformation of dihydroquercetin (DHQ). The physicochemical characteristics of DHQ oligomers synthesized using LC/IL did not differ from the characteristics of the oligomers obtained with native laccase. The synthesized oligomers have a number average molecular weight of 1050 g/mol and a polydispersity index of 1.41. Oligomers possess higher antioxidant activity than the monomer.
