Original Title:
Ανάπτυξη μεθόδου ποσοτικού προσδιορισμού ολικής trans - ρεσβερατρόλης σε οίνους με χρήση φασματοσκοπίας NMR
Translated title:
Developing a method of quantifying total trans-resveratrol content in wines using NMR spectroscopy
Summary:
Trans-resveratrol is a phenolic compound belonging to the family of stilbene, which is found in various parts of the grape. Resveratrol belongs to a broader class of compounds that have been identified as phytoalexins, since they are produced in living and abiotic stress conditions, such as microorganisms attacks or tissue damage from ultraviolet radiation, while being transported during the vinification to the must and the wine. Resveratrol has a strong antioxidant effect, ie neutralizes oxygenated roots and oxidative compounds produced in the various tissues or circulating in blood plasma and prevents oxidation of metals in the body.
In this respect, resveratrol has cardioprotective properties. According to newer studies, resveratrol appears to protect against the development of malignant tumors, inhibit the appearance and development of skin cancer and have anti-inflammatory properties
In this study we developed a novel and rapid method of quantifying the total trans-resveratrol content (in particular of total trans-resveratrolloids) in wines using NMR spectroscopy. Subsequently, 10 samples of the local red P.O.P. varieties Agiorgitiko, Xinomavro, Fokianos, Liatiko, Kotsifali, Mavrodaphni, Limnio and Moschato were analyzed and the content of total resveratrolloids was determined. These measurements showed that the highest content of resveratrol had Kotsifali, Xinomavro and Agiorgitiko, a fact also verified in older scientific publications.
