摘要: 以新鲜枸杞为原料,采用磁场法提取枸杞黄酮。在单因素试验基础上,通过正交试验优化磁场处理的条件。结果表明,在磁感应强度640mT、磁化时间40min、磁化温度65℃、浸提回流时间60min的条件下,枸杞黄酮的提取率可达到290.81mg/100g。

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
