| Abstract: | A
neutral polysaccharide(LBNP)is isolated and purificated from Lycium barljarum L.which is a
chinese traditional medicine plant. Structure analysis by Gas Chromatography and
Chro-matography-mass spectrometry shows that the sugur chain contains eight residues in all:
Xylose,Arabinose,annose,Galactose,Glucose,Erythrose,trace Fucose and Sorbinose. The molar
ratio of the former five monosaccharides is 10:1:1:6.7:4;LBNP is a rich branching
hetero-polysaccharide whose backbone composes of 1,4-linked Glucose,1,6-linked Galactose
and 1,4 or 1,5-linked Xylose, Branchings run out at C6 position of 1,4-linked Glucose of the
backbone and take Xylose and Galactose as their ending residues. In LBNP their are still one
kind of unrecog-nized linkage and some other trace linkages. |
