摘要: 采用正交设计法研究了提取温度、料液比、提取时间三因素对红枣提取的影响。初步筛选出优化水平组合为A2B2C3。同时对所得多糖经红外光谱、紫外光谱、纸层析法对其组成进行分析,并从脱色、除蛋白等方面对其纯化作了初步研究,结果表明:所得红枣多糖为单一成分,是由木糖、半乳糖组成;活性炭脱色,Sevag法去蛋白效果明显。

Abstract: Effect of temperature, proportion and time on extraction of the red dates polysaccharide were studied by orthogonalexperiment design and the optimum proportion A2B2C3 was chosen preliminarily. Meanwhile the author analyzed the componentof polysaccharide by infrared spectrum, ultraviolet spectrum and paper chromatography. The purification from the decoloration,removing proteins and others were deeply studied, the results showed that the red dates polysaccharide was a mono-ingredient,composed of D-Galactose and D-Xylose. The ways of active charcoal decoloration and proteins Sevag removing have significantefficiency.
