NEW MATERIAL:The protein polysaccharide having the following characteristics: composition, constituted of the saccharide parts consisting of amino sugar composed mainly of galactosamine and a neutral sugar composed of glucose, mannose and galactose, and the protein part having an amino acid composition of glutamic acid, aspartic acid, arginine, threonine, serine, etc.; elementary analysis, C 42-47%, H 5-8%, N 7-10%; molecular weight, 5,000-1,000,000 by gel-filtration; color reactions, positive to phenol sulfuric acid reaction, anthrone reaction, etc. and negative to Elson-Morgan reaction, etc.; specific rotation, [alpha]<20>D= +252 deg. (in 50mM acetic acid solution); exhibiting specific ultraviolet and infrared absorption spectra and proton NMR absorption spectrum. USE:It has carcinostatic, blood cleaning, and acidic protein coagulation effects, etc. PROCESS:The substance can be prepared by the liquid culture of fungi belonging to cordyceps genus, Ascomycetes class (e.g. cordyceps japonica IFO 9647, etc.). |
