紫萁多糖具有抗菌消炎活性 ,用酸水解、糖腈乙酸酯衍生化和气相色谱 (GC)分析法研究了紫萁多糖的单糖组成和摩尔比。结果表明 :紫萁多糖由葡萄糖 (Glu .)、甘露糖 (Man .)、木糖 (Xyl.)和半乳糖 (Gal.)组成 ,其摩尔比为 :Glu .∶Man .∶Xyl.∶Gal.=0 .17∶0 .33∶0 .4∶1,为进行紫萁多糖结构和功能相关性研究提供前期工作基础。
Ampelopsis polysaccharides have antibacterial and anti-inflammatory activity. The monosaccharide composition and molar ratio of Polysaccharides were studied by acid hydrolysis, glycocyanide acetate derivatization and gas chromatography (GC) analysis. The results showed that the purpura polysaccharide is composed of glucose (Glu.), mannose (Man.), xylose (Xyl.) and galactose (Gal.) and the molar ratio thereof is Glu.:Man.:Xyl.:Gal. .=0.17:0.33:0.4:1, providing preliminary work basis for the study of the structure and function of purpura polysaccharides.
