The Quito sun content polysaccharide, the production method, the medical supply and the food which include that are offered. After densely in the caustic alkaline aqueous solution, heating processing the mushroom, the liquid separating hard, melting the solid amount which is obtained in organic acid aqueous solution, this cause making precipitation including alcoholic or caustic alkali, washing and drying this precipitation the Quito sun content polysaccharide which can. This Quito sun content polysaccharide is the chemical compound which homo- polymer and gurukan of the glucosamine connect with covalent bond, constitution mol ratio of the glucosamine and glucose is, 1 - the 5:5 - 1 molecular weight approximately 150,000, (the 14) connection and (the 16) includes connection, but (the 13) connection it is not included. The protein or the restoration characteristic polysaccharide it is not included. This Quito sun content polysaccharide, is effective to the prevention and remedy of the life habit illness such as hypertension and diabetes.キトサン含有多糖、その製造方法、それを含む医薬品、食品を提供する。茸を濃苛性アルカリ水溶液中、加熱処理した後、固液分離し、得られた固形分を有機酸水溶液に溶解し、これにアルコール又は苛性アルカリを加えて沈殿を生じさせ、この沈殿を洗浄、乾燥して得られるキトサン含有多糖。このキトサン含有多糖はグルコサミンのホモポリマーと、グルカンが共有結合で結合した化合物であり、グルコサミンとグルコースの構成モル比は1~5:5~1であり、分子量約15万、β(1→4)結合及びβ(1→6)結合を含むが、β(1→3)結合を含まない。蛋白質及び還元性多糖を含まない。このキトサン含有多糖は、高血圧、糖尿病等の生活習慣病の予防及び治療に有効である。
