中文摘要：对新鲜和自然干燥后桃金娘的果实中的水溶性多糖进行了分离和化学构造初步研究。结果表明桃金娘多糖是木聚糖、阿拉伯半乳聚糖(AG)或者阿拉伯半乳聚糖糖蛋白(AGP)和果胶等构成的混合多糖。通过鲜果与干果实验数据的比较,其水溶性多糖的构成以及各组分含量均有明显变化。水溶性多糖分离纯化所得到的H3和H4组分的构成单糖分析表明,它们可能是含有较多毛发区域(鼠李半乳糖醛酸聚糖为主链)的果胶多糖。

外文摘要：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.
