Abstract

Most of the bitter compositions were separated from G. lucidum fruitbody through soaking, reflux and extraction by 95% alcohol solution before the extracting process of G. lucidum fruitbody polysaccharide (GFP). After alcohol extraction, the G. Lucidum fruitbody was water- extracted and the polysaccharide solution was concentrated as usual. The bitterness was also concentrated along with the concentration of the GFP solution. So the further reduction of the bitterness was necessary for the polysaccharide solution. It was proved in our experiment that the bitterness was reduced to the minimum level by supplementing 0.8% β- Cyclodextrin and 1.2% CMC - Na to concentrated G. lucidum fruitbody polysaccharide solution(1g crude drug/1mL GFP solution), and that β- CD and CMC- Na also had a stabilization effect on the concentrated G. Lucidum polysaccharide solution. And qualified material for further development of healthy products of GFP could be got drawing support from our experiment .

Key words
