TYPE A PROANTHOCYANIDINS FROM PRUNUS SPINOSA

Article abstract of DOI:10.1016/0031-9422(92)80312-3

Two proanthocyanidins were isolated from the branches of Prunus spinosa and identified as the known compounds, mahuannin A and ent-epiafzelechin-(2α->7,4α->8)-epicatechin.The structures were identified from spectroscopic data and CD studies.Hithero undescribed derivatives are described and the 13C NMR data were analysed using C-H bidimensional correlations and selective INEPT technique.
