Abstract: This work reports the application of magnetic field treatment to extract flavonoids from wolfberries. The optimal extraction conditions were determined by one-factor-at-a-time and orthogonal array design methods as follows: 40 min magnetic field treatment at 65 ℃ and 640 mT and then 60 min reflux solvent extraction. Under these conditions, the yield of flavonoids was 290.81 mg/100 g of wolfberries.

Key words: wolfberry flavonoids, magnetic treatment, organic solvent extraction
