Metabolite profiling of grape: Flavonols and anthocyanins.
Flavonols are products of the flavonoid biosynthetic pathway, which also give rise to anthocyanins and condensed tannins in grapes. We investigated their presence in the berry skins of 91 grapeExpand

Ripening and genotype control stilbene accumulation in healthy grapes.
In grapes, stilbene synthesis occurs in the skin, and it is induced by biotic and abiotic stresses. To date, experimental evidence of a constitutive production of resveratrols in healthy grape isExpand

Expression of the Stilbene Synthase (StSy) Gene from Grapevine in Transgenic White Poplar Results in High Accumulation of the Antioxidant Resveratrol Glucosides
When present, stilbene synthase leads to the production of resveratrol compounds, which are major components of the phytoalexin response against fungal pathogens of the plant and are highly bioactiveExpand

The Case for Anthocyanin Consumption to Promote Human Health: A Review.
Anthocyanins belong to the flavonoid group of polyphenolic compounds, which are responsible for the red and blue colors of plant organs such as fruits, flowers, and leaves. Due to their frequentExpand

Relationship of changes in rotundone content during grape ripening and winemaking to manipulation of the 'peppery' character of wine.
Biosynthesis of the sesquiterpene rotundone in Vespolina grapes during berry ripening was investigated over two consecutive seasons, revealing that the compound accumulates from veraison to harvestExpand

A versatile targeted metabolomics method for the rapid quantification of multiple classes of phenolics in fruits and beverages.
A targeted metabolomics method has been developed for the quantification of 135 phenolics, such as benzoates, phenylpropanoids, coumarins, stilbenes, dihydrochalcones and flavonoids, in fruit and tea extracts and wine using UPLC/QqQ-MS/MS. Expand
