The fruit body of Phellinus linteus was extracted with 80% aqueous MeOH, and the concentrated extract was successively partitioned using EtOAc, n-BuOH and $H_2O$. From the EtOAc and n-BuOH fractions, three phenolic compounds were isolated through repeated silica gel and ODS column chromatography. The chemical structures of these compounds were determined as 2-(3',4'-dihydroxyphenyl)-1,3-benzodioxole-5-aldehyde (1), 4-(3,4-dihydroxyphenyl)-3-buten-2-one (2), and protocatechuic acid methyl ester (3) by spectroscopic data including NMR, MS and IR. Compounds $1{\sim}3$ exhibited low density lipoprotein (LDL) antioxidant activity with $IC_{50}$ values of 1.7, 0.7, and $2.4{\mu}M$, respectively.
