Characterisation of highly polymerised prodelphinidins from skin and flesh of four cashew apple (Anacardium occidentale L.) genotypes Inra
Michodjehoun-Mestres, L.; Souquet, J.M.; Fulcrand, H.; Meudec, E.; Reynes, M.; Brillouet, J.M..
Tannins were extracted by acetone/water 60:40 from skin and flesh of four cashew apple genotypes from Brazil and Benin (West Africa), and separated from monomeric phenols. Tannins were submitted to acid-catalysed degradation in the presence of phloroglucinol and the products were analysed by HPLC-DAD/ESI-MS. Both skin and flesh tannins contained high percentages of (-)-epigallocatechin and (-)epigallocatechin-O-gallate, followed by minor quantities of (-)-epicatechin and (-)-epicatechin-3-O-gallate; 100% of the compounds were the 23-cis configuration. Skin tannins were half as galloylated (similar to 20%) than flesh tannins (similar to 40%). Their weight-average molecular weight (M-w) was high

El indio en la mente de los intelectuales criollos (Tema central) Buscador Latinoamericano
Gonz??lez, Osmar.
Los rasgos f??sicos funcionan como rasgos de diferencias sociales, llevando a asociaciones binarias del tipo blanco-bello, oscuro-feo; hombres superiores-hombres inferiores; desprecio-odio. Los rasgos f??sicos se vuelven importantes gracias a la valoraci??n que se les otorgan dentro del contexto de una cultura determinada.

Monomeric phenols of cashew apple (Anacardium occidentale L.) Inra
Michodjehoun-Mestres, L.; Souquet, J.M.; Fulcrand, H.; Bouchut, C.; Reynes, M.; Brillouet, J.M..
Monomeric phenols were extracted by acetone/water (60:40) from the skin and flesh of four cashew apple genotypes from Brazil and Benin (West Africa), purified by absorption chromatography and subjected to HPLC-DAD/ESI-MS analysis. Skins were found much richer than fleshes in simple phenolics. Flavonol glycosides were dominant with myricetin and quercetin hexosides (2 of each), pentosides (3 of each), and rhamnosides as majorcompounds. Anthocyanidin glycosides were detected in skins from the two scarlet and orange pigmented genotypes as peonidin, petunidin and cyanidin 3-O-hexosides, and were absent from fleshes

Validation of an extraction method on whole pericarp of grape berry (Vitis vinifera L. cv. Shiraz) to study biochemical and molecular aspects of flavan-3-ol synthesis during berry development Inra
Verries, C.; Guiraud, J.L.; Souquet, J.M.; Vialet, S.; Terrier, N.; Ollé, D..
An extraction method on grape berry was optimized for the total flavan-3-ol content measurement with regard to the nature of the sample and the duration of its extraction. This extraction was performed for the first time on the whole pericarp. Flavan-3-ol extractions were achieved on Shiraz ripe samples of pericarp versus skin within different durations: the best results were obtained for the whole pericarp and 1 h duration. Therefore, this more convenient protocol was used to investigate the flavan-3-ol content at different stages through berry development, in parallel with the abundance of transcripts involved in their biosynthesis. Furthermore, flavan-3-ol extractions on pericarp analysis confirmed their presence in both pulp and skin. For the first...
