[Methods]The isolated salvianolic acid M and rosmarinic acid were prepared into different concentrations of solutions for in vitro enzyme kinetics experiments. [Results]Salvianolic acid M and rosmarinic acid had the strongest inhibition effects at the concentration of 1 g/L. [Conclusions]Salvianolic acid M and rosmarinic acid have inhibition effects on human aldose reductase. The IC50 of salvianolic acid M is 0. 79 μg/mL,and that of rosmarinic acid is 1. 13 μg/mL.展开更多
