A range of flavanols and proanthocyanidin dimers were isolated and identified from Lotus
pedunculatus. The more abundant polymeric proanthocyanidins were also isolated and their …

The chemical structure of the purified proanthocyanidin polymers of Lotus corniculatus was
analysed by 13C NMR and by mild acid catalysed degradation in the presence of excess of …

The blood-red sap of Croton lechleri was found to contain proanthocyanidins as major
constituents which accounted for up to 90% of the dried weight. In addition to (+)-catechin,(−) …

In a chemical investigation of the bark of Quercus dentata gallic acid,(+)-catechin,(+)-
gallocatechin, hexagalloyl glucose and five proanthocyanidin dimers namely catechin-(4α→ …

Proanthocyanidin (PA) polymers (condensed tannins) were extracted from sainfoin leaves
(Onobrychis viciifolia Scop.) at different stages of plant development. Analysis of the …

The structures of 38 proanthocyanidin polymers (condensed tannins) from 14 widely
distributed families of plants are described. The polymers have been isolated from a wide …

Proanthocyanidin (PA) polymers (condensed tannins) were isolated and purified from the
leaves of 26 accessions and species of sainfoin (Onobrychis). Analysis of the degradation …

Structural complexity in the condensed tannins (polymeric proanthocyanidins) is centered
principally on variations in hydroxylation patterns of the flavan chain extender units, the …

The proanthocyanidin (PA) chemistry of 12 Lotus species of previously unknown PA content
was examined in comparison with agricultural cultivars of L. pedunculatus, L. corniculatus …

A proanthocyanin has been isolated from avocado seed. The compound resembles those
that have been isolated from other sources in its ready hydrolysis into catechin and the …
