摘要
将甜荞、苦荞粉碎后乙醇浸提法提取黄酮类化合物,其黄酮粗提物的得率分别为1.39%和2.76%,粗提物中黄酮含量分别为0.589%和3.22%.以BHT和Vc为阳性对照,研究两种荞麦黄酮粗提物对植物油和动物油的抗氧化效果.结果表明,两种荞麦黄酮粗提物具有显著的抗氧化性能,其中苦荞黄酮粗提物在两种油脂中的抗氧化性高于BHT和Vc.
The flavonoids compounds were extracted from the Fearta esculenium and Fearta tartaricum by using ethanol extraction method.The extraction rate of flavonoids were 1.39% and 2.76%,and the flavonoids content of the two kinds of buckwheat were 0.589% and 3.22%.Then the antioxidant activities in vegetable oil and animal oil were studied.The results showed the flavonoids extraction from Fearta esculenium had significant antioxidant function,but it was slightly lower than BHT.Flavonoids extraction from Fearta tartaricum had excellent antioxidant activities,which was higher than BHT and Vc.
