Abstract: The extraction technology of honeybee pupa flavonoides by ultrasound and it’s antioxidation in vitro were studied in this research. The results showed that it costs short time to extract honeybee pupa flavones by ultrasound with a good effect. The optimum extraction technology is ultrasound intensity 34 W/cm2, extraction time 20 min, ratio of material to solvent 1:15 with methanol as the solvent. The extraction amount of honeybee pupa was 43.85 mg/100 g. The honeybee pupa flavonoids have distinct inhibition against O2· made by alkaline pyrogallic acid, ·OH produced by Fenton reaction, LO·and LOO· peroxidation reaction of PUFA of yolk LDL induced by Fe2+, and dosage-effect correlations exist.

Key words: honeybee pupa, flavones, ultrasound, extraction, antioxidation
