正交试验优化磁场法提取枸杞黄酮工艺

摘要

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 yie, ld of flavonoids was 290.81 mg/100 g of wolfberries.%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。
