Abstract: The optimal extraction conditions of total flavonoid from Hydrocotyle sibthorpioides var were obtained by orthogonal test. The content of total flavonoid was determined by UV method. The results showed that the yield of total flavonoid was 2.67% at the conditions of 50% ethanol solution, 80℃,1:30 solid-liquid ratio and 1 h for extraction.

Key words: Hydrocotyle sibthorpioides var, flavonoids, orthogonal test, extracting method
