Abstract

Four flavonoids were isolated from the heartwood of Prunus sargentii. The structures were identified by NMR spectroscopic analysis: prunetin as isoflavone, angophorol, and sakuranetin as flavanone, and isosakuranin as flavanone glycoside. However, these compounds indicated low antifungal and antioxidative activities. In this regard, it could suggest that high antifungal and antioxidative activities of extractives of P. sargentii have no ralationship with these compounds.
