Abstract: Jujube dates were extracted with water,and then 95% ethanol was used to remove proteins and polysaccharides from the extraction in order to separate and purify oligosaccharide. By sephadex-G15 column chromatography,fractionⅠand Ⅱ were obtained from the extracts. According to HPLC analysis,the average molecular weight of oligosaccharide is estimated to be 3951. The result of IR spectrometry showed that it is a pyranose.

Key words: Zizyphus jujube, oligosaccharide, isolation, structure
