Abstract: The ultrasonic extraction process of total flavonoids from Damnacanthus indicus(Linn) Gaertn.F.,was optimized by L9(34) orthogonal test design in this study.The results showed that the optimal extraction conditions are as follows:70 % alcohol as extraction solvent,ratio of material to liquid 1:25,extraction temperature 50 ℃ and extraction time 40 min.Under these conditions,the extraction rate of total flavonoids is 15.01 mg/g.

Key words: Damnacanthus indicus(Linn) Gaertn.F., flavonoids, ultrasonic extraction, orthogonal test design
