Antitumor activity of water-soluble .BETA.-D-glucan elaborated by Ganoderma applanatum.

Abstract

have been isolated from a numberof sources, such as yeast, 1.5 ~1.0 0.5 G-I -2O/3 o Mv-## fungi, lichens, bacteria, and plants. In general, highly branched fungal and yeast glucans having /?-(l ->6)-D-glucopyranose units on a /?-(l->3)-D-glucan backbone are known to be antitumor active.1} Also, antitumor glucans from Basidomycetes having a /?-(l ->3)-linked backbone and branches involving a-(l->4)-
