Objective: To investigate flavonoids from Artocarpus hypargyreus.
Method: The compounds were isolated by various chromatographic methods and identified by spectroscopic analysis.
Result: 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).
Conclusion: Compound 1 is a new isoprenylated flavone, while compounds 2, 4-6, and 8 were isolated from this plant for the first time.
