Three fractions of polysaccharides that have high biological activity were extracted from Chinese bamboo leaves (Indocalamus Tesselatus) with 0.9% sodium chloride, 1% ammonium oxalate and 85% ethanol. Their component sugars were investigated by paper chromatography developed with
Polysaccharides prepared from Chinese traditional medicine "Ruoye" (Indocalamus tesselatus), a kind of bamboo leaves, were studied. Eight crude polysaccharides were isolated from the dried leaves by successive extraction with 85% ethanol (FE), 0.9% sodium chloride (FS), hot water (FI), 1% ammonium
For preparation of sulfated polysaccharides isolated from bamboo leaves (Indocalamus tesselatus) with chlorosulfonic acid-pyridine, the experimental conditions as the molar ratio of reactants and temperature and time of reaction were discussed. A homogeneous sulfation method with good yield of more
