Abstract
From the heartwood of Rhus verniciflua, four known flavonoids (1-4) were isolated along with an unknown one (5). Compounds 1-4 were identified to be garbanzol, sulfuretin, fisetin and fustin by NMR data. NMR data of 1-4 were fully assigned by the aids of 2D-NMR spectra. Among these compounds, only sulfuretin had significant cytotoxic and antioxidant ability at high concentrations. In addition, it seems likely that the 5-hydroxy-lacking flavonoids could not influence on the activity of laccase with cofactor of cupric cation, which catalyzes oxidative coupling reaction, in this plant.
