【摘要】 采用溶剂法及大孔树脂法提取卫矛中降血糖及抗心肌缺血有效部位的总黄酮,通过紫外分光光度法测定总黄酮含量,利用抑制邻苯三酚自氧化试验考察抗氧化性。结果表明,卫矛中降血糖和抗心肌缺血有效部位的总黄酮含量分别为:3.055%±0.068%和38.80%±0.066%,两种部位均显示出抗氧化活性。卫矛降血糖和抗心肌缺血作用可能都与其抗氧化作用有关。更多还原

【Abstract】 To extract two efficient parts with macroreticular resin;To determine the content of total Flavonoids with UV-spectrophometry.To measure their anti-oxidation by means of pyrogallol oxidation.The results showed that total flavonoids in two efficient parts are 3.055%±0.068% and 38.80%±0.066% respectively;both parts have activity of anti-oxidation.Functions of decreasing blood sugar and anti-myocardial ischemia have something to do with the anti-oxidation action.更多还原
