Quercus Humboldtii (Colombian Oak): Characterisation of wood phenolic composition with respect to traditional oak wood used in oenology
[EN] The use of new oak barrels and the demand for oak wood in oenology is increasing. Thus, it is necessary to search for new wood sources to supply the current demand in cooperage. The aim of this work was to study the composition of ellagitannins and low molecular weight phenolic compounds (LMWP) by HPLC-DAD of green wood Quercus humboldtii Bonpl. (Colombian), compared to the species typically used in cooperage: Quercus sessiliflora Salisb. (French and Romanian) and Quercus alba L. (USA). In Colombian oak wood, the same LMWP and ellagitannins as in the traditional species were identified. The most abundant LMWP was ellagic acid, and its concentration was lower in Q. humboldtii and Q. alba than in Q. sessiliflora, so these two presented a lower content of phenolic acids. As regards phenolic aldehydes, Colombian oak wood only showed significant differences in the content of coniferyl and sinapic aldehydes in relation to French oak. Finally, the total ellagitannin content of Q. humboldtii was lower than that of European oaks and similar to that of American oak (Q. alba). None of the ellagitannins studied presented significant differences compared to Q. alba. Therefore, Q. humboldtii wood was more similar in terms of phenolic composition to Q. alba than to Q. sessiliflora.

[PT] O uso de novos barris de carvalho e a procura de madeira de carvalho em enologia estão aumentando. Assim, torna-se necessária a investigação de novas fontes de madeira para satisfazer a atual procura pela tanoaria. O objetivo deste trabalho foi estudar a composição de taninos elágicos e compostos fenólicos de massa molecular baixa (LMWP) por HPLC-DAD de madeiras verdes de Quercus humboldtii Bonpl. (colombiano), em comparação com espécies tipicamente usadas em tanoaria: Quercus sessiliflora Salisb. (francês e romeno) e Quercus alba L. (EUA). Na madeira de carvalho da Colômbia, foram identificados os mesmos LMWP e taninos elágicos do que nas espécies tradicionais. O LMWP mais abundante foi o ácido elágico, e sua concentração foi menor em Q. humboldtii e Q. alba do que em Q. sessiliflora, portanto estas duas madeiras apresentaram menor teor de ácidos fenólicos. Em relação aos aldeídos fenólicos, a madeira de carvalho colombiano mostrou diferenças significativas no teor de aldeídos coniferílico e sinápico em relação ao carvalho francês. Finalmente, o conteúdo total de taninos elágicos de Q. humboldtii foi inferior ao dos carvalhos europeus e semelhante ao do carvalho americano (Q. alba). Nenhum dos taninos elágicos estudados apresentou diferenças significativas relativamente a Q. alba. Assim, a composição fenólica da madeira de Q. humboldtii assemelha-se mais à da madeira de Q. alba do que à de Q. sessiliflora. This work was funded by Grant Nº 11150462 from Fondecyt, Chile.
