Abstract:
1. A bear bile macromolecular extract with anti-hepatitis C virus function, characterized in that the extract is prepared by the following method: add water to dissolve bear bile powder to obtain aqueous solution of bear bile in concentration of 10˜100 mg/ml, centrifuge the solution by a molecular sieve filter membrane with molecular weight cut-off of 100,000 at the centrifugal force of 4000×g for 10˜60 minutes, or centrifuge fresh bear bile by a molecular sieve filter membrane with molecular weight cut-off of 100,000 at the centrifugal force of 4000×g for 1˜2 hours; filter to obtain a sediment, dissolve the sediment in water to obtain a solution, add the solution to a pretreated cross-linked dextran column having a dry particle size of 40 μm-120 μm and a globular protein fractionation range of 4×10
