초록

Two new benzylated flavonoids, 5,7,4'-trihydroxy-6-p-hydroxybenzylflavanone (1) and 5,7,4'-trihydroxy-6,8-di-p-hydroxybenzylflavanone (2) together with six known flavonoids, kaempferol (3), artocarpesin (4), cycloartocarpesin (5), cudraflavone D (6), gericudranin E (7), and leachianone G (8) have been isolated from the root bark of Cudrania tricuspidata. The structures of 1 and 2 were characterized based on spectroscopic data including 1D- and 2D-NMR. All the isolates were evaluated for their inhibitory effects of monoamine oxidase (MAO). Among them, kaempferol (3), artocarpesin (4), and cudraflavone D (6) showed moderate inhibitory effects with $IC_{50}$ values of 82.3, 30.8, and $71.8\;{\mu}M$, respectively.
