To investigate flavonoids from Artocarpus hypargyreus. The compounds were isolated by various chromatographic methods and identified by spectroscopic analysis. Ten compounds were isolated and their structures were identified as artohypaflavone (1), brosimone H (2), artonin A (3), artocarpin (4), artopetelin B (5), (-)-epiafzelechin (6), oxyresveratrol (7), (+)-afzelechin (8), (+)-catechin (9), and (+)-afzelechin-3-O-alpha-L-rhamnopyranoside (10). Compound 1 is a new isoprenylated flavone, while compounds 2, 4-6, and 8 were isolated from this plant for the first time.
