| Abstract: | The optimum conditions of extraction polysaccharide from Pleurotus ostreatus were studied. The results showed that the optimal technology conditions of extraction were: the mass ratio of Pleurotus ostreas to water was 1∶30,distilling at 90℃ for 8 hours, volume fraction of ethanol is 80% when precipitated by ethanol. The orthogonal trial showed that the effect of isolation protein by Seveg method was the best in the mixture composed of 50% (chloroform + n-butanol) (volume fraction) with V(chloroform)/V(n-butano) l0∶3, 30 min, the extraction rate is 1.54% |
