     an ionic liquid (il)-containing buffer system was first applied in the conversion of rutin to isoquercitrin. high substrate solubility was achieved to enhance the selectivity and efficiency of hesperidinase-catalyzed reaction. ten ils were selected as co-solvents to assist catalytic reactions in this biotransformation process. the transformed products of rutin were identified by lc–ms. the [bmim][bf4]-glycine-sodium hydroxide buffer (ph 9) (10:90, v/v) was found to be the best medium for the biotransformation of isoquercitrin from rutin with higher selectivity and efficiency. the reaction time was reduced by 0.33-fold while the conversion of rutin and the yield of isoquercitrin were increased by 1.67-fold and 2.33-fold. the results suggest that il co-solvents have great potential to enhance the selectively enzymatic hydrolysis of rutin for isoquercitrin production.
