Toona sinensis,which is called "green health food", has many effective ingredients including quercetin, kaempferol, rutin and other flavonoids.It has obvious pharmacological effects on the protection of the ardiovascular system, the endocrine system, the immune system and anti-tumor, and so on.Eight types of ionic liquids were synthesized in this paper.And then microwave-assisted extraction method, which is one of the advanced method for extracting active ingredients from herbs, was used to extract quercetin from Toona sinensis.Ionic liquids, a class of friendly green solvents to the environment, were used as the extraction solvents instead of traditional organic solvents.A method for determining the content of quercetin in Toona sinensis by HPLC was established.
