摘要: The root bark, stem bark and leaves of Terminalia macroptera were sequentially extracted with ethanol, 50% ethanol-water, 50 °C 100 water using an accelerated solvent extractor. Ten bioactive purified polysaccharide fractions obtained from those crude extracts after anion exchange chromatography gel filtration. polysaccharides their native characterized respect to molecular weight, chemical compositions effects in the complement assay. showed that are pectic nature. results indicated there was no great difference fixation activities different plant parts when extracting extraction system. 100WTSBH-I-I 100WTRBH-I-I isolated respectively, highest activities. These two have rhamnogalacturonan type I backbone, but only contains side chains both arabinogalactan II. Based on yield studied gave results, followed by bark. But total, all materials good sources for containing polysaccharides.
