The hot-water extract of fruiting bodies in Fomitella fraxinea had potent anti-complementary activities. After fractionation of water-soluble polysaccharides by DEAE-Sephadex A-25 column chromatography, major anti-complementary activity was concentrated into the FF-AP1 among three polysaccharides (FF-NP, FF-AP1, FF-AP2). FF-AP1 was fractionated into $FF-AP1{\alpha}$ and $FF-AP1{\beta}$ obtained from the adsorbed fraction and unadsorbed fraction by affinity chromatography using a ConA-sepharose 4B column, respectively. $FF-AP1{\beta}$, which exihibited the highest anti-complementary activities had an IR absorption peak of $890cm^{-1}$, and a M.W. of about 15,000 (gel filtration). Anti-complementary activity of FF-AP1 decreased greatly by pronase treatment and periodate oxidation. $FF-AP1{\beta}$ responsible for potent anti-complemenary activities of Fomitella fraxinea was an acidic protein-containing heteroglycan consisted of 48% glucose, 13% mannose, and 12% galactose as major component sugars, 9.6% protein, 6% uronic acids.
