Proanthocyanidins fromAntenoron neofiliforme

Planta Medica, 1989
Six compounds have been isolated and characterized from the rhizomes of Antenoron neofiliforme: procyanidin B2-3'-0-gallate, procyanidine B2, (-)-epicatechin-3-0-gallate, (-)-epicatechin, (+)-catechin and gallic ...

Oligomeric proanthocyanidin glycosides ofClementsia semenovii

Chemistry of Natural Compounds, 1998
The structures of proanthocyanidins CS-3 and CS-4, isolated from the roots ofClementsia semenovii have been established on the basis of chemical and spectral studies. CS-3 is 7-O-(6-O-galloyl-β-D-Glcp $$\xrightarrow{6}$$ O-β-D-Glcp

Oligomeric proanthocyanidin glycosides ofRhodiola pamiroalaica. II

Chemistry of Natural Compounds, 1998
In a continuation of investigations of proanthocyanidins of the roots ofRhodiola pamiroalaica, we have isolated proanthocyanidins RP-3 and RP-4. Their compositions, structures, and relative configurations have been investigated: RP-3 is 7-O-(6-O-galloyl-β-D-Glcp)-3-O-galloyl-(-)-epigallocatechin-(4β-8)-[(-)-epicatechin-(4β-8)-(3-O-galloyl ...

Flavans and proanthocyanidins

1988
Haslam’s previous accounts of this area of flavonoid chemistry (Haslam, 1975, 1982a) eloquently summarized the historical developments in the chemistry and biochemistry of this important and complex group of plant phenolics. Also covered were their relationship with condensed tannins and aspects of their characteristic chemical and spectroscopic ...

Proanthocyanidins in cereals and pseudocereals

Critical Reviews in Food Science and Nutrition, 2018
Proanthocyanidins (PAs) are a class of oligomeric flavonoids found in a variety of plant foods. Intake of PAs in human diet has been associated with a reduced occurrence of various chronic disorders. Cereal and pseudocereal grains are staple food items.

Biflavonoids and Proanthocyanidins

1989
The biflavonoids and proanthocyanidins constitute the two major classes of oligomeric flavonoids found in plants (126, 136). The biflavonoids are oxidative coupling products leading to biflavones, flavanone-flavones, and biflavanones. These compounds always carry carbonyl functions at the C-4 positions (126).
