In this experiment, the effect of hydrophilic nano titanium dioxide on the total flavonoids yield of peanut hull was investigated. Meanwhile, the extraction conditions were optimized. The result showed as followed. Adding hydrophilic nano titanium dioxide into solvent might increase the total flavonoids yield of peanut shell. The most suitable conditions for extraction of total flavonoids from peanut hull through adding 5 mg of hydrophilic nano titanium dioxide in 15 ml dissolvant, were sample to solvent ratio 1:15, ethanol concentration 70%, temperature 55℃, and 65 minutes. Under the best condition, the total flavonoids yield of peanut hull was 2.97 mg/g.
