Triflavonoids of Ochna calodendron

Phytochemistry. 2002 Feb;59(4):435-8. doi: 10.1016/s0031-9422(01)00414-9.

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