| 摘 要： | 通过乙醇沉淀、透析、离子交换和凝胶色谱等分离方法,我们从白花蛇舌草中分离得到一种葡聚糖HD-27,ESI-MS检测其分子量为1800。利用化学及光谱分析方法进行结构研究,确定HD-27是由11个葡萄糖残基组成,其结构为α-D-G lc-(1→4)--αD-G lc-(1→4)]9-β-D-G lc。

| Abstract: | OBJECTIVE: To isolate a homogeneous polysaccharide RP from RDP (a crude polysaccharide from Dioscorea opposita Thunb.), and study its preliminary com-position and structure. METHODS: RP was obtained with water extraction, alcohol sedimentation, CTAB deprotein, cellulose column and SephadexG-100 column. The purities of RP were identified by SephadexG-200. PC analysis on its acidic hydrolysates was used to determine the sugar components. Sephadex chromatography was used to mensurate its molecular weight. IR was used to analysis RP. RESULTS: RP was homogeneous. IR indicated that RP had P configurations. The compositon was identified by paper chromatography as glucose, D-mannose, D-galactose. CONCLUSION: The research could provide a theoretical foundation for further development and utilization. |
