A neutral polysaccharide and an acidic polysaccharide have been isolated from the dried fruits of Zizyphus vulgaris LAMARCK var. inermis BUNGE. The former, named Zizy-phus-arabinan, possesses one mole of D-galactose per thirty moles of L-arabinose residues. As the results of methylation and periodate oxidation studies, it is able to concluded that the arabinan has a chain of 1 5 1inked α-L-arabinofuranose units having a highly branched structure with 1 2 branch point. The component sugars of the acidic polysaccharide were D-galacturonic acid, L-rhamnose, L-arabinose, D-xylose and D-galactose.
