Abstract

Abstract: JS₁ is the water soluble polysaccharide isolated by alkaline from Hippophae rhamnoides L.. By means of IR, GC, GC MS, ¹³C NMR, periodate oxidation, Smith degradation, mathylation analysis and partial acid hydrolysis etc., JS₁ is a kind of neutral heteropolysaccharide with many branches. It consists of Ara, Xyl, Gal and Glc in a molar ratio of 1:6:12:4 in turn. Its basic structure consists of a main chain composed of(1→3) linked Xyl,(1→3) linked Gal and (1→3) linked Glc residues with side chains of (1→5) linked Xyl, (1→4) linked Gal and (1→6) linked Gal residues, attached to C-2 of Xyl and C-6 of Gal residues in the main chain.

Key words: Hippophae rhamnoide L., Hippophae rhamnoides polysacharide, Structure
