Structural analysis was made on the glucan moiety of purified antitumor active polysaccharide fraction H11 obtained from the mycelia of P. cocos. In the 13C-nuclear magnetic resonance spectrum of fraction H11, signals at 102.9 and linked D-glucosyl redidues, respectively. On addition of NaOD solution, the C-1 signal was separated into two signals at 104.2 and 104.8 ppm which can be assigned to the C-1 filtration method with CPG-1000A. Complete methylation and hydrolysis of fraction H11 gave
