Triflavonoids of Ochna calodendron

Phytochemical investigation of the dichloromethane extract of Ochna calodendron leaves resulted in the isolation and identification of three known isoflavones, irilone, 3′-methoxyirilone and prunetin, one cyanoglucoside, menisdaurin, in addition to two new triflavonoid constituents, namely caloflavans A and B. The structures of the new compounds were established by spectroscopic methods (EI-MS, FAB-MS, 1H NMR, 13C NMR, HMBC and HMQC)

Further isoflavonoid metabolites from Millettia griffoniana (Bail)

Three new isoflavonoids, griffonianone A (1), B (2) and C (4) were isolated from the root bark of Millettia griffoniama, along with the known maximaisoflavone G (5) and 7-hydroxy-6- methoxy-3',4'-methylenedioxyisoflavone (6). Their structures were assi
