Abstract:
PURPOSE: A method for preparing chitosan saccharide is provided to remove polymer materials and to improve antibacterial effects. CONSTITUTION: A method for preparing chitosan saccharide of middle molecular weight with antibacterial effects comprises: a step of mixing malt enzyme extract in to acidic solution containing chitosan with 70-99% of deacetylation to obtain chitosan solution; and a step of dialyzing the chitosan solution to remove insoluble materials. The chitosan of middle molecular weight has an antibacterial effect against gram-positive bacteria.
Abstract:
PURPOSE: A pharmaceutical composition containing extract having antiviral activity, which is obtained from Phellinus pini is provided to suppress enzyme activity relating to viral infection mechanism and to prevent viral diseases. CONSTITUTION: A pharmaceutical composition for preventing or treating diseases by infection of coxsackievirus, influenza virus, or herpes simplex virus contains Phellinus pini-derived antiviral extract as an active ingredient. The extract is obtained from a fruit body of the Phellinus pini by adding polar solvent and centrifuging. The polar sovent is alcohol of 1-4 carbon atoms. The extract is contained in a concentration of 0.001-5.0 mg/ml. The extract contains water soluble polysaccharide of beta-(1,3)(1,6)-glucan.
