In the course of screening lipid peroxidation inhibitor from basidiomycetes, a mushroom, which was collected at O-Dae mountain in Kangweon- Do, was found to have active compound. The mushroom was identified as Polyzellus multiplex, which belongs to Aphylloporalles Thelephoraceae, on the basis of macroscopic and microscopic characteristics of the fruiting body. The methanol extract of fruiting body was extracted with benzene and ethylacetate, sequentially. By using various kinds of chromatographies, PM1, and PM2 and PM3, were purified from the ethylacetate extract and the benzene extract, respectively. Color reaction and analyses of IR, UV, and NMR spectra indicated that PM1 was a derivative of thelephoric acid, and PM2 and PM3 were linoleic acid and oleic acid, respectively. IC$_{50}$ of PM1 for inhibition of lipid peroxidation was 1.96 ppm and LD$_{50}$ was 500 mg/kg.
