Abstract: Flavonoids were extracted from the Chrysanthemum monfolium Ramat by pressurized liquid extraction. Conditions including extraction temperature, ratio of material to liquid, the ethanol concentration, extraction time, and extraction pressure were studied by using single factor analysis method. The optimal process conditions were obtained by orthogonal analysis as follows: the extraction temperature 70℃, ratio of material to liquid 1:60, the ethanol concentration 60%, extraction time 40 min and extraction pressure 0.25 MPa. The yield of extraction was 8.07﹪. Compared with the flavonoids extracted by traditional refluxing extraction, the flavonoids extracted by the pressurized liquid extraction had a similar elimination function on DPPH·radical with the traditional refluxing extraction.

Key words: Chrysanthemum monfolium Ramat, flavonoid, pressurized liquid extraction, anti-oxidation
