【摘要】 利用大孔吸附树脂分离纯化山楂黄酮并确定合适的工艺参数,同时以比色法测定其含量,并对山楂黄酮的抗氧化活性做了初步研究。结果表明,HPD-100大孔吸附树脂对山楂黄酮分离纯化效果较好,吸附解析后山楂黄酮纯度达到56.9%,添加量0.002%山楂黄酮能有效延缓葵花籽油的氧化,效果与0.001%TBHQ相当。更多还原

【Abstract】 To separate and purify the water soluble Hawthorn flavones and to establish the optimum technological parameters of purification.The content of flavones was determined by colorimetry and antioxidant activity was also studied.The results showed the HD-100type of macroreticular resid had the better comprehensive property,the flavones purity was 56.9% in sample and antioxidant activity was better than TBHQ for sunflower oil.更多还原
