Structure Research on the Polysaccharides of Rhodomyrtus tomentosa Fruit (I)

Abstract

Abstract: Isolation and characteritic structure of water-soluble polysaccharides in Rhodomyrtus tomentosa were studied. The results suggested that it contained the constitutents of several polysaccharides consisting of xylan, arabinogalactan (AG) or arabinogalactan-protein (AGP), pectin and others. By comparing the fresh with air-dried fruit, the obvious difference of polysaccharide constituent and their content could be found. The results of sugar analysis of H3 and H4 indicated that there was probably a special pectin polysaccharide having a hairly region with its backbone a rhamnogalacturonan.

Key words: Rhodomyrtus tomentosa, polysaccharides, arabinogalactan-protein (AGP), rhamnogalacturonan
