title: An A-type proanthocyanidin from Prunus armeniaca.
abstract: Roots of Prunus armeniaca yielded a new A-type proanthocyanidin whose structure was assigned as ent-epiafzelechin-3-O-p-hydroxybenzoate-(4alpha-->8, 2alpha-->O-->7)-epiafzelechin (1). The structure of 1 was determined through extensive 1D and 2D NMR studies.
