NODES - SPOKE 6 Project VINO - D4.2 - Report on the chromatographic methodology set up to draw the extract's fingerprint

Herein we report on the development of a rapid and low solvent consuming HPLC-UV/PAD analytical methodology suitable for the analysis of Vitits vinifera pruning wood extracts and for the quantitation of their main secondary metabolites, E-Resveratrol and E-ε-Viniferin. Specifically, for quantification purposes, the method was validated in terms of linearity, detection limit (DL) e quantitation limit (QL), repeatability for both the analytes. This document is a deliverable of the project VINO ("VIneyard management for viNeprOduction"), which proposes research for sustainable innovation supported by the digitalisation of the wine sector with the primary objective of creating new solutions and readapting existing practices to cope with the effects of climate change in viticulture. This document is part of the project NODES which has received funding from the MUR – Missione 4, Componente 2, Investimento 1.5 – Creazione e rafforzamento di “Ecosistemi dell’innovazione”, costruzione di “leader territoriali di R&S'' – del PNRR funded by the European Union - NextGenerationEU with grant agreement no.
