ANTITUMOR AGENT HAVING PEPTIDE HETERO POLYSACCHARIDE SEPARATED FROM CRUSHED CELL WALL OF CHLORELLA PYRENOIDOSA AS ACTIVE INGREDIENT

To provide a novel antitumor agent.SOLUTION: An active ingredient of an antitumor agent is peptide hetero polysaccharide with high molecular weight which is obtained by processing a crushed cell wall of Chlorella pyrenoidosa by hot-water extraction, removing a low-molecular substance having the molecular weight of 10000 or less from its hot-water extraction liquid, and then purifying it, in which a saccharide composition has galactose as a main constituent, and furthermore, has glucose, mannose, xylose, rhamnose, arabinose and fructose as other constituents.SELECTED DRAWING: None 【課題】新たな抗腫瘍剤を提供する。【解決手段】クロレラ・ピレノイドサの細胞壁破砕物を熱水抽出処理し、その熱水抽出液から分子量１００００以下の低分子物質を除去した後、精製処理して得られる、糖組成がガラクトースを主構成成分とし、更にグルコース、マンノース、キシロース、ラムノース、アラニノース及びフラクトースを他の構成成分とする高分子量のヘプチドヘテロ多糖体を、抗腫瘍剤の活性成分とした。【選択図】なし
