| 摘 要： | 目的]研究豌豆多糖的抗氧化活性和抑菌活性。方法]采用Fenton法、Tris-HCl法、DPPH法测定豌豆多糖抗氧化活性;采用滤纸片扩散法测定豌豆多糖对藤黄八叠球菌、变形球菌、金黄色葡萄球菌、枯草芽孢杆菌的体外抑菌作用。结果]豌豆多糖对羟基自由基、超氧负离子自由基和DPPH自由基都有一定的清除能力,但清除效果弱于抗坏血酸;豌豆多糖对藤黄八叠球菌、变形球菌、金黄色葡萄球菌具有明显的抑制作用,但对枯草芽孢杆菌的抑制作用不明显。结论]试验证实了豌豆多糖具有抗氧化性和抑菌活性。

| Abstract: | Objective] To study the antioxidant activity and antibacterial activity of pea polysaccharide(PP).Method] The antioxidant activity of PP was detected by using the methods of Fenton,Tris-HCl and DPPH;the method of filter paper diffusion was adopted to measure the in vitro inhibition effect of PP against Sarcina lutea,Proteus vulgaris,Staphylococcus auteus and Bacillus subtilis.Result] PP could remove hydroxyl radicals,DPPH radical and superoxide anion radical,but its removal effect was weaker than Vc;PP h... |
