Abstract

The technological conditions of extracting total flavonoids from chrysanthemum straw with supercritical carbon dioxide were studied. When the carbon dioxide flow was 20 L/h,the effects of process parameters,such as raw material size,pressure,extraction temperature and extraction time, were investigated. The results showed the optimal extraction conditions as follows: raw material size 60 meshes,extraction temperature 50 ℃,extraction time l00 min and pressure 25 MPa.
