根据测得的黄酮类化合物对油脂的过氧化值 ,研究了黄酮类化合物抗氧化性与其结构的关系 .结论是B - 4′-OH为强活性基 ,B - 2′、3′、5′、6′-OH和A - 7-OH为增效基 ,用共振理论与诱导效应讨论了黄酮类化合物有无C - 2 ,3双键 ,其抗氧化性几乎不变的原因
According to the measured peroxide value of flavonoids to oil, the relationship between the antioxidant activity and the structure of flavonoids was studied.The conclusion is that B - 4’- OH is a strong active group, B - 2 ’, 3’, 5 ’ , 6’-OH and A - 7-OH as synergetic groups, the reasons for the almost unchanged antioxidant activity of flavonoids with or without C - 2 and 3 double bonds were discussed with resonance theory and induction effect
