From the bark of Artocarpus rigida Bl. (Moraceae), collected in Indonesia, two new isoprenylated flavones, artonins G (1) and H (2) were isolated along with three known isoprenylated flavones, artonin E (3), cycloartobiloxanthone (4), and artobiloxanthone (5). The structures of artonins G and H were shown to be 1 and 2, respectively, on the basis of spectroscopic data.
