English: The phenolic content of the heartwood of Peltophorum africanum (African wattle) and Burkea africanum (Red syringa) proved to contain a variety of compounds including the novel 4-arylflavan-3-ol lactones, ...
Photochemistry of (+)-catechin and (-)-epicatechin
(University of the Free State, 2008-01)
Despite the well known fact that photolysis of free phenolic catechins give rise to isomerisation at the C-2 position (e.g. (-)-cis epicatechin converts to the sterically less hindered (-)-trans isomer), researchers have ...
