Abstract: 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.
