Two new special flavones from Uvaria accuminata

From the stem bark of Uvaria accuminata two new compounds, 5-methoxy-6,8,8-trimethyl-2-phenylchromene-4,7-dione (1) and a sesquiterpene-fused flavone, named acuminavone (2), were isolated together with a known flavone, desmosdomutin or dasytrichone, (5-hydroxy-6,8,8-trimethyl-2-phenylchromene-4,7-di...

Summary:From the stem bark of Uvaria accuminata two new compounds, 5-methoxy-6,8,8-trimethyl-2-phenylchromene-4,7-dione (1) and a sesquiterpene-fused flavone, named acuminavone (2), were isolated together with a known flavone, desmosdomutin or dasytrichone, (5-hydroxy-6,8,8-trimethyl-2-phenylchromene-4,7-dione) (3). The structure elucidation of compounds 1 and 2 in spectroscopic studies is described.
