TL;DR: The structures of sericic acid and sericoside, the major constituents of the roots of Terminalia sericea, have been determined as discussed by the authors, and they are 2α,3β,19α,24-tetrahydroxy-olean-12-en-28-oic acid, and their corresponding C -28 D -glucosyl ester.

TL;DR: The use of these polyphenol fractions, alone or in combination with other active principles, is of interest to the food, pharmaceutical and cosmetic fields as discussed by the authors, and they can be used alone or combined with lipophilic antioxidants, sulfurated amino acids and oligoelements.

TL;DR: In this article, a process for producing a purified extract from Ginkgo biloba leaves by solvent extraction with selected solvents is described, in which a crude or partially purified extract is subjected to solvent extraction using a solvent comprising toluene and n-butanol.

TL;DR: Procyanidol oligomers almost free from monomers are obtained by subjecting the vegetal extracts (for instance from Vitis vinifera) to ultrafiltration on membranes of cut-off from 3.000 to 600, or to a selective extraction with mixtures of esters or ethers and aromatic hydrocarbons as discussed by the authors.

TL;DR: In this paper, an extract enriched in procyanidol oligomers almost free from monomers is obtained by subjecting a crude vegetable extract, for instance from Vitis vinifera, to ultrafiltration on membranes of cut-off from 3,000 to 600, or to a selective extraction with ethers, or esters or mixtures of ethyl acetate and aromatic hydrocarbons.
