摘要

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。

[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.
