摘要
目的本文对红树植物桐花树中多糖的提取及其组成进行了研究。方法桐花树叶经热水浸提、Sevage法脱蛋白等方法得到多糖;经完全酸水解,糖腈乙酸酯衍生化,并用红外光谱仪、气质联用仪对其结构和组成进行了研究。结果桐花树多糖由D-核糖、D-阿拉伯糖、D-木糖、D-甘露糖和D-葡萄糖组成。结论桐花树多糖为杂多糖。
OBJECTIVE Study on the polysaccharide extraction process and monosaccharide Constitution from Aegiceras corniculatum.METHODS Polysaccharide was extracted by means of hotwater and purified by Sevegmethod to remove protein;their structural composition was studied by complete acid hydrolysis and aldoononitrile acetate derivatives and GC-MS,IR.RESULTS The polysaccharide was composed of D-ribose,D-arabinose,D-xylose,D-mannose and D-glucose.CONCLUSION Polysaccharide of this plant is a heteropolysaccharide.
