摘要
本文研究了红枣多糖的沉淀条件,并对所提取的红枣多糖粗品的抗氧化作用进行了探讨。结果表明:红枣多糖的沉淀条件为浸提液浓缩4倍,加入4倍体积的乙醇,使最终乙醇浓度达80%;红枣多糖能提高小鼠血液、肝脏及脑组织中超氧化物歧化酶(SOD)和过氧化氢酶(CAT)活性,降低小鼠血液、肝脏及脑组织丙二醛(MDA)含量,表明红枣多糖体内具有抗氧化作用。
The optimum precipitation conditions of Jujube date polysaccharide were obtained as follows： The extracting liquid was concentrated 4 times, adding 4 times volume ethanol and making the final concentration of alcohol 80%. The polysaccharides from jujube Mill could raise the activities of SOD, CAT and decrease the amount of MDA in blood, liver and brain of rats.
