The use of acacia wood for the aging of vinegars is increasing because the efficient air transfer through the pores permits a good acetification rate. In this study, vinegars aged in acacia (Robinia pseudoacacia) wood barrels were analyzed and found to contain a characteristic compound, which increased during the aging process. This so far unknown compound was isolated by semipreparative LC and structurally identified by NMR spectroscopy. (1)H and (13)C NMR chemical shifts and optical rotation… Expand
Phenolic composition of vinegars over an accelerated aging process using different wood species (acacia, cherry, chestnut, and oak): effect of wood toasting.
Wood shavings are widely employed in vinegar making to reduce aging time. Accordingly, this study aims to evaluate the effects of using shavings from different wood species (acacia, cherry, chestnut,Expand
Gram-Scale Purification of Dihydrorobinetin from Robinia pseudoacacia L. Wood by Centrifugal Partition Chromatography
Robinia pseudoacacia L. is a tree widely dispersed in France that is characterized by good growth rates and important biomass production, which produces wood with very high natural durability usedExpand
Effect of toasting intensity at cooperage on phenolic compounds in acacia (Robinia pseudoacacia) heartwood.
Toasting changed the chromatographic profiles of extracts spectacularly, and the toasted acacia wood contributed flavonoids and condensed tannins (prorobinetin type) in inverse proportion to toasting intensity, while LMW phenolic compounds were directly proportional to toasted intensity, except for gallic and ellagic acid and related compounds.

Polyphenols in red wine aged in acacia (Robinia pseudoacacia) and oak (Quercus petraea) wood barrels.
Although longer contact time with acacia wood mean higher concentrations of phenolic markers found in wines, the identification of these wines will also be easy after short aging times due the high levels reached by these compounds, even after only 2 months of aging. Expand
Polyphenolic profile as a useful tool to identify the wood used in wine aging.
Toasting notably changed the phenolic composition of acacia, chestnut, cherry, cherry and ash heartwoods proportionally to toasting intensity and led to a minor differentiation among species in toasted woods, although the authors also found phenolic markers in toasting woods. Expand
Wood impregnation of yeast lees for winemaking.
This study develops a new method to produce more complex wines by means of an indirect diffusion of wood aromas from yeast cell-walls, and demonstrates the potential of using woods other than oak in cooperage. Expand
Determination of (+)-Dihydrorobinetin as An Active Constituent of the Radical-Scavenging Activity of Asana (Pterocarpus marsupium) Heartwood
Asana used in Ayurveda medicine originates from the heartwood of Fabaceae Pterocarpus marsupium. In our previous report, we demonstrated that a 50% ethanolic extract (PM-ext) of Asana was a promisingExpand
Yuccalechins A–C from the Yucca schidigera Roezl ex Ortgies Bark: Elucidation of the Relative and Absolute Configurations of Three New Spirobiflavonoids and Their Cholinesterase Inhibitory Activities
The ethyl acetate fraction of the methanolic extract of Yucca schidigera Roezl ex Ortgies bark exhibited moderate acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) inhibitory activityExpand
Phenolic compounds released from oak, cherry, chestnut and robinia chips into a synthetic wine: influence of toasting level
Advantages and drawbacks from the use of oak chips in oenology are well documented; wood oenological value is primarily related to cooperage potential, and not addressed from the oenologist view;Expand
Polyphenolic compounds as chemical markers of wine ageing in contact with cherry, chestnut, false acacia, ash and oak wood.
The nonanthocyanic phenolic composition of four red wines, one white, and one rosé aged using barrels and chips of cherry, chestnut, false acacia, ash and oak wood was studied by LC-DAD-ESI/MS, toExpand
