Abstract: Response surface methodology(RSM)was applied to optimize ultrasonic-assisted extraction process of total flavonoids from Rubus corchorifolius L.f.Based on single experiments,extraction times,the concentration of ethanol and ultrasonic temperature were selected for BoxBehnken central composite design.RSM was employed to study the effect of these factors on the yield of total flavonoids.The results indicated that the optimal process conditions were to extract 2 times,76% of aqueous ethanol,with 44 ℃ of ultrasonic temperature.Under these optimized conditions,the extraction yield of total flavonoids was up to 12.39 mg/g.

Key words: Rubus corchorifolius L.f, total flavonoids, ultrasonic-assisted extraction, response surface methodology
