Land-adapted plants appeared between about 480 and 360 million years ago in the mid-Palaeozoic
era, originating from charophycean green algae. The successful adaptation to land …

Dietary polyphenols show a great diversity of structures, ranging from rather simple
molecules (monomers and oligomers) to polymers. Higher-molecular-weight structures (with …

LC-mass spectrometric analysis of the degradation products released by thioacidolysis of a
grape (Vitis vinifera var. Merlot) skin extract showed that catechin, epicatechin, epicatechin …

Extracts containing anthocyanins (ACN), and skin tannins (SKIN) and seed tannins (SEED)
were prepared from Vitis vinifera cv. Cabernet Franc grapes grown in the Loire Valley, and …

Five tannin fractions were isolated from grape (Vitis vinifera) seeds. HPLC analysis of the
degradation products released by thioacidolysis showed that all fractions consisted of catechin, …

A high performance liquid chromatography (HPLC) method to investigate the flavonol composition
of grape skins was developed using Cinsault grapes. In addition to the expected main …

Flavonoids protect plants against various biotic and abiotic stresses, and their occurrence in
human diet participates in preventing degenerative diseases. Many of the biological roles of …

Grape phenolics are structurally diverse, from simple molecules to oligomers and polymers
that are usually designated “tannins,” referring to their ability to interact with proteins. …

A range of structurally defined apple and grape proanthocyanidins was isolated in sufficient
amount to carry out a formal sensory descriptive analysis study. Purified proanthocyanidin …

Phenolic compounds are a large class of plant secondary metabolites, showing a diversity
of structures, from rather simple structures, eg phenolic acids, through polyphenols such as …
