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.
结果表明，包含在疏水性离子液体（IL）中的漆酶（LC）可重复用于二氢槲皮素（DHQ）的生物转化。使用LC/IL合成的DHQ低聚物的物理化学特性与用天然漆酶获得的低聚物的特性没有差异。合成的低聚物的数均分子量为1050 g/mol，多分散指数为1.41。低聚物比单体具有更高的抗氧化活性。
