The polysaccharide of lentinus edodes and polytictus versicolor has been fractionated by repeated precipitation method. Modified elias cloud-point tiualion method by using an Abbe refrectormeter to determine the cloud-point. It was found that water/acetone (89:11 by volume) is a θ-solvent for the polymer at 25℃.
