摘　　要：采用微波法提取金莲花中黄酮类化合物,并采用HPD-300大孔树脂对粗提液进行精制,精制物中黄酮含量比粗提物中黄酮含量明显提高。在自由基清除试验中,精制金莲花黄酮类化合物表现出较强的自由基清除能力,并且精制后的金莲花黄酮类化合物自由基清除能力高于未精制的产品,精制物对自由基的清除效果接近抗坏血酸的作用效果。This paper mainly studied on extracting flavonids from gold lotus by microwave and purifying the products by macroporous resins of HPD-300.The result of oils anti-oxygenation experiment showed that the purified product was much better than the unpurified product in the quality and ability of anti-oxygenation.
