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).
