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.

Key words: red date, polysaccharide, extraction, separation procedure, orthogonal experiment
