鱼腥草水溶性多糖的提取及鉴定

本试验结果表明，鱼腥草茎水溶性多糖的最佳提取条件为：热水浸提３次，每次４ｈ，浸提１００℃，乙醇含量为８５％，以聚丙烯酰胺凝胶电泳证明为杂多糖。薄层层析法鉴定多糖组分是葡萄糖，果糖，阿拉伯糖、半乳糖、木糖鼠李糖及另一种未知的五碳糖。

Study on Extraction and Assessment of Polysaccharide Hydrolysates of Houttuynia Cordata Thunb

The experiment of extracting technology of the polysaccharide hydrolysates of Houttuynia cordata Thunb was conducted as follows extracting 3 times in hot water 4 hours each time and separating the polysaccharide by alcohol in 85 percent density. The components of the polysaccharide were identified by polyacrylamide gel electrophoresis and thin layer chromatography. The polysaccharide was assessed to be a heteroglycan compsed of glacose fructose arabinose galactose xylos?rhamnose and unkown pentaglucose.
