Extraction and antioxidant activity of carboxymethylated garlic polysaccharide were investigated. The crude polysaccharide was extracted by the hot-water method. The peak appearing around 177 in C NMR spectrum should be attributed to carbonyl group, indicating that the preparation of carboxymethylated garlic polysaccharide was successful. Moreover, it was proved that the carboxymethylated garlic polysaccharide had the potential scavenging ability to superoxide anions and hydroxyl radicals. So, it should be a potential antioxidant.
研究了羧甲基化大蒜多糖的提取及其抗氧化活性。采用热水法提取粗多糖。C NMR 谱中约 177 处的峰应归因于羰基，表明羧甲基化大蒜多糖的制备是成功的。此外，还证明羧甲基化大蒜多糖具有超氧阴离子和羟自由基的潜在清除能力。因此，它应该是一种有潜力的抗氧化剂。
