Characterization of water soluble polysaccharides from organs of Chinese Jujube (Ziziphus jujuba Mill. cv. Dongzao)

Water-soluble polysaccharides (WSPs) in Chinese jujube leaves, fruits and flowers were extracted with hot water from the alcohol insoluble residues (AIRs) and precipitated with ethanol allowed to concentrate the fraction as 7.8, 5.1, 18.3%. Pectic polysaccharides were the major components in all WSPs since all extractions were very rich in sugars such as uronic acid, arabinose and galactose. Polymers extracted with hot water from different organs were different in the degree of branching, degree of esterification. All WSPs revealed immunobiological activities especially in fruits and flowers.http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000252942500006&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701Food Science & TechnologySCI(E)EI38ARTICLE5985-98922
