摘要：

A new methoxylated isoflavone, 7,4'-dihydroxy-5,3',-dimethoxyisoflavone, named gerontosioflavone A, together with 12 known flavonoids, wighteone, genistein, genistein 5-methyl ether, orobol, B-C-prenylorobol, 6-C-prenylapigenin, 8-C-prenylapigenin, naringenin, 5,7,2',4'-tetrahydroxyflavanone, artocarpesin, kaempferol and aromadendrin, and a new prenylated xanthone, 4',5'-dihydro-5,6-dihydroxy-1-methoxy-4' (2',3': 3,2) xanthone named gerontoxanthone J, together with kaempferol-7-glucoside and kaempferol-3,7-diglucoside, were isolated from root wood and root bark of the Formosan medicinal plant, Cudrania cochinchinensis var. gerontogea. The structures of the two new compounds were established by 2D NMR techniques.
