[Flavonoids from Artocarpus hypargyreus].
OBJECTIVE
To investigate flavonoids from Artocarpus hypargyreus.


METHODS
The compounds were isolated by various chromatographic methods and identified by spectroscopic analysis.


RESULTS
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).


CONCLUSIONS
Compound 1 is a new isoprenylated flavone, while compounds 2, 4-6, and 8 were isolated from this plant for the first time.
