title: [Experimental studies on the extract technology of tea polysaccharide from green tea by orthogonal test].
abstract: The effect factor of extraction of tea polysaccharide was investigated with orthogonal test. The effects of extraction conditions on yield, purity of tea polysaccharide and cost of extraction were discussed. The results show that the optimum conditions for extracting tea polysaccharide from green tea are as follows: extraction time is 30 minutes with water at 95 degrees C, extraction times with chloroform is 3, extraction times with CH3COOC2H5 is 1 and concentration of alcohol is 60%.
