Extraction of volatile and semi‐volatile components from oak wood used for aging wine by miniaturised pressurised liquid technique

International Journal of Food Science & Technology, 2009
SummaryA miniaturised pressurised liquid technique has been applied to the extraction of volatile compounds present in oak wood samples used in making wine. The solvent extraction performed at high pressure and temperature has allowed the detection of a large number of compounds some of which present sensory and antioxidant properties.

Concurrent Measurement of O2 Production and Isoprene Emission During Photosynthesis: Pros, Cons and Metabolic Implications of Responses to Light, CO2 and Temperature

Plant, Cell &Environment, EarlyView.
ABSTRACT Traditional leaf gas exchange experiments have focused on net CO2 exchange (Anet). Here, using California poplar (Populus trichocarpa), we coupled measurements of net oxygen production (NOP), isoprene emissions and δ18O in O2 to traditional CO2/H2O gas exchange with chlorophyll fluorescence, and measured light, CO2 and temperature response ...

Volatile Compounds in Spanish, French, and American Oak Woods after Natural Seasoning and Toasting

Journal of Agricultural and Food Chemistry, 2003
The volatile composition (volatile phenols, phenolic aldehydes, furanic compounds, lactones, phenyl ketones, and other related compounds) of Spanish oak heartwood of Quercus robur, Quercus petraea,Quercus pyrenaica, and Quercus faginea was studied by gas chromatography/mass spectrometry, in relation to the processing in barrels cooperage and in ...

Molecular evolution of terpene synthase underlying the diversification of isoprene emission in Fagaceae

Plant Biology, EarlyView.
Isoprene emission in oaks originated from convergent adaptive evolution of terpene synthases, involving a substrate shift from monoterpene to isoprene production within a Fagaceae‐specific TPS lineage. Abstract Plants emit a wide range of volatile organic compounds, among which isoprene is the most abundant and atmospherically influential. Although oak

Mikroorganismen an Aesculus hippocastanum – olfaktorische Perspektive von Cameraria ohridella (Deschka & Dimic)

, 2008
Since the 80s, the popular park- and city tree Aesculus hippocastanum has been infested with the leaf miner Cameraria ohridella (DESCHKA & DIMIC 1986). Additionally, the pathogenic fungi Guignardia aesculi causes leaf blotch disease and Erysiphe flexuosa

The role of volatile cues in mediating tree host-bacteria-insect interactions in acute oak decline

Acute oak decline (AOD) is a decline syndrome affecting native oaks in the UK, characterized by bacterial stem lesions and larval galleries of the beetle Agrilus biguttatus.

Oak extract application to grapevines as a plant biostimulant to increase wine polyphenols

, 2014
Oak extract is a mixture of compounds including phenolics (volatiles and non volatiles), which could act as plant biostimulant if they are able to modulate plant physiological response.

Knowledge gap on the spatial structure of soil nitrogen mineralization variability—A systematic review

Agricultural &Environmental Letters, Volume 11, Issue 2, December 2026.
Abstract Soil nitrogen (N) mineralization governs plant‐available N from soil organic matter and microbial turnover, and is typically estimated as potentially mineralizable nitrogen (PMN) via anaerobic incubations or as N0 and mineralization rate (k) via long‐term aerobic incubations.

Volatile Compounds in Acacia, Chestnut, Cherry, Ash, and Oak Woods, with a View to Their Use in Cooperage

Journal of Agricultural and Food Chemistry, 2009
Extracts of wood from acacia, European ash, American ash, chestnut, cherry, and three oak species (Quercus pyrenaica, Quercus alba and Quercus petraea) before and after toasting in cooperage were studied by GC-MS. 110 compounds were detected, and 97 of them were identified.
