| 摘 要： | 采用热水浸提法从大蒜中提取大蒜粗多糖（GA），用DEAE一纤维素柱层析对GA进行纯化，得到中性多糖（GB）和酸性多糖（GC）。进一步对3种大蒜多糖的抗氧化性进行测定，结果显示：GB具有较好的清除羟基自由基和还原能力，GC具有较好的清除超氧阴离子自由基和配位能力，而GA的抗氧化能力则介于GB和GC之间。

| Abstract: | Crude garlic polysaccharide(GA) was extracted from garlic by hot-water extraction.GA was further isolated into neutral garlic polysaccharide(GB) and acidic garlic polysaccharide(GC) through the DEAE-cellulose column.On this basis,the antioxidation of the three garlic polysaccharides was evaluated.The results show that GA,GB and GC exhibit different antioxidation and GA always shows moderate activity between GB and GC.The neutral polysaccharide GB shows the highest hydroxyl radical scavenging and reductive activity,whereas the acidic polysaccharide GC exhibits highest superoxide radical scavenging and iron ion chelating activity. |
