“…The authors also observed significant differences depending on the vineyard of origin (in this case, two exploitations). These variations could also rely on several parameters such as UV-exposition and soil compositions (Guerrero et al, 2010;Acuña-Avila et al, 2016). Diverse viticultural practices as leaf removal or fertilizer use could also be responsible for such stilbenes contents variations (Keller et al, 2000;Cavaliere et al, 2010).…”

Viticultural wood waste as a source of polyphenols of interest: Opportunities and perspectives through conventional and emerging extraction methods

Viticultural waste has been widely demonstrated to contain high-added value compounds named the stilbenes. Among them, trans-resveratrol (Rsv) and trans-εviniferin (Vf) are the most abundant in particular in grape canes. Various emerging methods such as ultrasound-assisted extraction (UAE), microwave-assisted extraction (MAE) or pressurized solvent extraction (PSE) have been studied to recover Rsv and Vf from grape canes in order to enhance their extraction. This paper gives a critical overview of the techniques used to this end, integrating conventional and nonconventional methods investigated in the literature as well as those used in industrial processes. It finally highlights that the unconventional technics are usually less timeconsuming than conventional extraction ones but further investigations for the discussed compounds and biomass are needed to optimize and understand the influence of the individual parameters of each extraction process.

“…The UV-exposition of vineyards depending directly of their location impacts the stilbenes accumulation in grape canes as well as the soil composition or the fungal pressure. [30][31][32] Viticultural practices, as leaf removal, irrigation or nitrogen fertilization and differing from a vineyard to another, could also be responsible for these variations. 33,34 Impact of particles size.…”

Viticultural by-products are known to contain high-value compounds such as stilbenes. Wine sector in Savoie Mont Blanc region (France) generates high amount of waste including grape canes and grapevine stocks that remain unvalued. Herein, the potential of the most widespread grapevine varieties in Savoie Mont Blanc territory, Jacquère and Mondeuse, as sources of two stilbenes, trans-resveratrol (Rsv) and trans-ε-viniferin (Vf) was investigated for the first time. Using the reported extraction technique, the present work focused on several preextraction parameters influencing the extraction efficiency, including grapevine variety, age of 2 vines, time of material storage and particles size of the woody material. This work revealed important Rsv and Vf contents in Jacquère residues of 1681-6124 mg.kg-1 dw and 1620-6667 mg.kg-1 dw respectively, whereas for Mondeuse variety, the target molecules yields were 1724-4636 mg.kg-1 dw and 1713-5322 mg.kg-1 dw respectively. These results are promising when compared with high well-known stilbenes levels in Pinot Noir and Gewurztraminer varieties but also highlight a considerable variability depending on the applied pre-extraction parameters.

“…The trans -stilbenes belong to the group of the polyphenolic phytoalexins that are synthesized in plants as a response to stress; these compounds are naturally occurring in many fruits such as grapes [1,2,3] and berries [3,4,5], which are used in the production of commercial juices.…”

Trans-stilbenes belong to the group of polyphenolic phytoalexins, and occur in many plant foods. These compounds have received great attention by researchers due to their well-known beneficial health effects. In the present study a chromatographic method that comprises the use of variable wavelength (VWD) and fluorescence (FLD) detectors in series for the analysis of trans-stilbenes is presented. The relation of peak-area obtained with both detectors is proposed as an alternative and complementary approach for the rapid identification of these phenolic compounds. The proposed method was applied to determine trans-stilbenes in commercial fruit juices. Trans-piceid was the most common trans-stilbene found in the samples analyzed. The method was validated in terms of linearity, sensitivity and repeatability. Appropriate sensitivity and good linearity (r2 > 0.9991) were achieved.
