Triflavonoids of Ochna calodendron

Abstract 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, 1 H NMR, 13 C NMR, HMBC and HMQC).
