Abstract： The water extract of fructus Schisandra was treated by four kinds of clarifying agents namely glutin,starch,fresh egg white,chitosan.Its light transmittance was determined at 680nm,and the clarification effects of the four agents were compared at different concentration,time and temperature.The results showed that among the four agents,glutin and chitosan had preferable clarification effect compared with fresh egg white,while the clarification effect of starch could be ignored.The optimal clarification effect was obtained when treating the water extract of fructus Schisandra with 0.16% glutin or 0.08% chitosan.The light transmittance were 84.02% and 84.44% respectively.The clarifying speed of fresh egg white was slower than that of glutin and chitosan,and temperature had nearly no influence on the clarification effect of fresh egg white and chitosan.As a contrast,the clarification effect of glutin dropped as temperature increased.
