Chemical constituents from Ouratea floribunda: complete 1H and 13C NMR assignments of atranorin and its new acetyl derivative

Chromatographic fractionation of the hexane extract from the wood of Ouratea floribunda (Ochnaceae) afforded friedelin (1), friedelanol (2), lupeol (3) and the depside atranorin (4). The structure elucidation of the isolated compounds was performed by spectrometric analysis involving comparison with...
