The optimum conditions for ultrasound-assisted extraction flavonoids from red dates was stud-ied. Orthogonal experiments showed that the best extraction technology of Xinjiang red dates:the ethanol concentration was 50%,extraction time was 50 min,the solid to liquid ratio was 1 :30 g/mL,the yield of flavonoids extraction was 8. 91 mg/g. Shanbei red dates optimum extraction of 60% ethanol,extraction time was 50 min,the solid to liquid ratio was 1 :20 g/mL,the yield of flavonoids extraction was 18. 56 mg/g. The flavonoids extraction from Xinjiang and Shanbei red dates had strong scavenging capacity to O2-· and ·OH.
