Abstract: The extraction and anti-oxidation of the flavonoid from Dicrano pteris pedata was studied. The result showed that, the best extracting condition is: ultrasonic wave 20min, alcohol concentration 50%, temperature 85℃ and extracting 1.5h. The flavonoid had good anti-oxidation to the hydroxyl free radical and the oxygen free radicals.

Key words: flavonoid, Dicrano pteris pedata, ultrasonic wave, free radical
