研究了黄花软紫草水溶性多糖的提取及对Fenton反应产生·OH自由基的清除效果。结果表明,以水为溶剂提取的紫草多糖的得率为2.53%,且此粗多糖清除自由基的能力与其浓度呈线性关系。
The extraction of water-soluble polysaccharides from S. breviflora and the removal of OH radicals from Fenton reaction were studied. The results showed that the yield of lithospermum polysaccharide extracted with water as solvent was 2.53%, and the ability of the polysaccharide to scavenge free radicals was linear with the concentration.
