Abstract: The flavonoids content in flowers of Coreopsis basalis was determinated by use of the color metric method with rutin as standard material. The analytical result showed that the average content of flavonoids in flowers of Coreopsis basalis was 25.99%, and the method for determining flavonoids content of Coreopsis basalis is simple and useful, meanwhile the determination repeatability is very good. The optimum extracting conditions were: extract temperature 85℃, extract time 1.5h, extract for 3 times with the extraction reagent 65% alcohol.

Key words: Coreopcis basalis, total flovonoids, extract
