This paper takes flavonoids the Mountain chrysanthemum leaves contained as the research object, using ultrasonic to extract total flavonoids and using response surface methodology to optimize flavonoids of mountain chrysanthemum leaves extraction process. The experiment use normal pressure silica gel column chromatography to isolate flavonoids, and take some tests to monomer and total flavonoids, for example of in vitro and in vivo antioxidant activity tests, the study of hypoglycemic activity and antibacterial activity etc. The purpose is to screen the active ingredient (monomers) of mountain chrysanthemum leaves.
