云芝多糖是由采绒革盖菌(Coriolus Ver-sicolor)中提取的糖蛋白。由于它对实验肿瘤有抑制效果,对细胞无毒性,可口服等优点,而引起人们注目。1965年日本吴羽化学工业公司研究各种担子菌提取物的抗癌活性,由211种担子菌中筛选出较有希望的云芝。1966年对其化学成份进行鉴定,1972年进行云芝提取工艺研究,并将其提取物命名为PSK。经过二年多药理临床试验,认为它具有提高机体免疫功能,抑制肿瘤作用。1977年供售市场,自上市之后,销售量一直上升,据称1981年该厂云芝多糖(FSK)销售额高达571亿日元,占日本十大
Coriolus versicolor is a glycoprotein extracted from Coriolus Ver-sicolor. Because of its inhibitory effect on experimental tumors, non-toxic cells, can be oral and other advantages, which attracted people’s attention. In 1965, Kure Chemical Co., Ltd. of Japan studied the anticancer activities of various basidiomycetes extracts and screened out more promising polysaccharides from 211 basidiomycetes. Its chemical composition was identified in 1966. In 1972, its extraction technology was studied, and its extract was named as PSK. After more than two years of pharmacological clinical trials, that it has to improve the body’s immune function, inhibit tumor effect. Sales in 1977 for the market, since the listing, sales have been rising, in 1981, the plant allegedly polysaccharides (FSK) sales of up to 57.1 billion yen, accounting for Japan’s top ten
