    (Alternative Title) Structural elucidation of an atropoisomeric entcassiflavan-(4beta-->8)-epicatechin isolated from Dalbergia monetaria L.f based on ECD calculations in comparison to experimental data
    Description:
    (Abstract) A rare dihydoxyflavan-epicatechin proanthocyanidin, entcassiflavan-(4  8)-epicatechin, has been isolated from Dalbergia monetaria, a plant widely used by traditional people from the Amazon to treat urinary tract infections. The constitution and relative configuration of the compound were elucidated by HR MS and detailed 1D and 2D NMR measurements. By comparing the experimental electronic circular dichroism (ECD) spectrum with the calculated ECD spectra of all 16 possible isomers, the absolute configuration, the interflavan linkage and the atropisomers could be determined.
