The medicinal mushroom Inonotus obliquus is a traditional and widely used multi-functional fungus. In the present study, the lipophilic fraction of Inonotus obliquus were investigated for their antioxidative activity with hydroxyl radical scavenging activity assays. As a result, two acidic materials had higher antioxidative activity than basic or neutral materials. Furthermore, antioxidative acidic materials including organic acids were isolated by silica gel column chromatography and subsequent preparative high-performance liquid chromatography. Two purified antioxidants, designated compound 1 and 2, were identified as vanillic acid and syringic acid, respectively. Vanillic acid and syringic acid were showed the antioxidative activities with IC_50 values of 59.0 and 2.8 μg/ml, respectively.
