PURPOSE:To obtain the titled drug capable of promoting the function of a chemotherapeutical drug by medicating the titled drug and the chemotherapeutical drug, etc. to a patient with reduced immune function, by comprising a polysaccharide PS-C which is extracted from a plant of the genus epimedium, isolated and purified, as an active ingredient. CONSTITUTION:A mixed solvent of water and an organic solvent (e.g., lower alcohol, etc.) compatible with water is added to a plant of the genus epimedium to give an aqueous extracted solution. An organic solvent compatible with water in any ratio is added to the solution to give a precipitate, which is dissolved in water. A long-chain quaternary ammonium salt is added to the solution, formed compounded substances are removed, the solution is purified by chromatography, etc., to give the desired fraction. Elemental analysis: C 40.75, H 6.28, ash trace amount. Molecular weight: 25,000+ or -15,000. Properties of substance: white slightly brown amorphous powder. Decomposition point: 175 deg.C pH: 7.0. Constitutional saccharide: found to have physical and chemical properties of arabinose, galactose, etc., and immnue enhancing action. |
