ABSTRACT

Phellinus linteus mycelia have many pharmacological effects although their pharmacological efficacy principles have not been known before. In the course of screening for biological activity of the extracts of Ph. Linteus mycelia, we found strong antioxidative activity in the extract. Therefore, we tried to isolate the active principle(s) from the extract. The isolation of the active compound was guided by superoxide anion radical scavenging activity. As a result, caffeic acid was isolated as an active compound. The IC50 of the compound was 3.05 μg/mL (16.9 μM).
