Powder of a macrofungus. Grifola frondosa(GF) was prepared from the white s tipes. The biomaterial was washed with acetone and distilled water, and sli ghtly transparent white powder of GF was obtained. In the presence of the G F powder, the polymerization of acrylamide (AAm) was carried out in distill ed water with eerie ion in nitric acid as an initiator. The reaction produc t was precipitated in acetone, filtrated, and dried. The yield calculated f rom the mixture of polyacrylamide-GF increased with an increase of temperat ure and the amount of the GF used. The mixture was washed with distilled wa ter, and the solubilization % into water was determined. The reaction of AA m onto the surface of the GF facilitated the solubization in water. The H-1 NMR of GF without or with water/acetone washing and the filtrate of GF or GF-Polyacrylamide (PAAm) mixture was measured. It was estimated that higher fatty acids were extracted with acetone from GF, while alpha -type polysac charides or that including PAAm were extracted with water. However, it was difficult to extracrt beta -type polysaccharides with water.
