【 摘 要 】

In this study, flavonoids were obtained from Lotus (Nelumbo nuficeraGaertn) leaf using ultrasound-assisted extraction method (UAE). Optimum extraction conditions of flavonoids from Lotus leaf (FLL) were investigated through single factor test and orthogonal test. Its anti-fatigue activity was evaluated by swimming test. The results showed that the optimal extraction parameters were as followings: concentration of ethanol solution was70% , ratio of solvent to raw material was 35, ultrasound time was 25 min. Swimming test results suggested that FLL had significant anti-fatigue activity.
