Relevant aspect of wine geog. origin is related to grapevine varieties used for wine production in specific wine country or region. The grapevine germplasm is highly variable and classified into geog. groups. These classifications were recently confirmed using genetic studies, and further classified varieties into geog.-genetic (GEN-GEO) groups. Polyphenolic compounds are important secondary metabolites in grapes and have an important impact on wine quality and sensory properties. The aim of this research was to investigate the polyphenolic profiles of 50 grape varieties from different GEN-GEO groups. The groups were C2 (varieties from Italy and France), C7 (varieties from Croatia), C8 (varieties from Spain and Portugal). Polyphenolic compounds analyzed belonged to the classes of anthocyanins, flavan-3-ols, flavonols, phenolic acids, and stilbenes. The most abundant classes of polyphenols were anthocyanins, followed by flavan-3-ols and flavonols. Using discriminant anal., the genetic-geog. groups were clearly separated based on their polyphenolic profiles, with all classes of compounds contributing to discrimination. In the experiment, the researchers used many compounds, for example, (E)-4-(3,5-Dihydroxystyryl)benzene-1,2-diol (cas: 10083-24-6Recommanded Product: 10083-24-6).
(E)-4-(3,5-Dihydroxystyryl)benzene-1,2-diol (cas: 10083-24-6) belongs to alcohols. Alcohols are among the most common organic compounds. They are used as sweeteners and in making perfumes, are valuable intermediates in the synthesis of other compounds, and are among the most abundantly produced organic chemicals in industry. Tertiary alcohols cannot be oxidized at all without breaking carbon-carbon bonds, whereas primary alcohols can be oxidized to aldehydes or further oxidized to carboxylic acids.Recommanded Product: 10083-24-6
