Abstract

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.

用固定在离子液体中的漆酶聚合双氢槲皮素。

结果表明，疏水离子液体(IL)中的漆酶(LC)可重复用于二氢槲皮素(DHQ)的生物转化。用LC/IL合成的DHQ低聚物的理化性质与用天然漆酶合成的低聚物的理化性质没有差异。所合成的低聚物的数平均分子量为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。
