Metabolite profiling of grape: Flavonols and anthocyanins.
TLDR
The presence of laricitrin 3-O-galactoside and syringet in red grapes is reported here for the first time and it is indicated that the enzyme flavonoid 3',5'-hydroxylase is not expressed in white grape varieties.

Quantitation of polyphenols in different apple varieties.
TLDR
Forty-one apple samples, representing eight of the most widely cultivated varieties in western Europe, were collected in Trentino, Italy to achieve a good extraction of polyphenols, including proanthocyanidin oligomers which were analyzed by normal-phase HPLC.

Evolution of gut microbiota composition from birth to 24 weeks in the INFANTMET Cohort
TLDR
These findings confirm that mode of delivery and gestational age both have significant effects on early neonatal microbiota composition and there is also a significant difference between the metabolite profile of FT and PT infants.

The Case for Anthocyanin Consumption to Promote Human Health: A Review.
TLDR
The aim of this body of work is to investigate and review the current literature on anthocyanins, and particularly their pharmacokinetics and any health-promoting properties, in order to summarize existing knowledge and highlight any aspects that require further study and analysis.

Profiling and accurate quantification of Rubus ellagitannins and ellagic acid conjugates using direct UPLC-Q-TOF HDMS and HPLC-DAD analysis.
TLDR
This survey of ellagitannins and ellagic acid conjugates provides evidence for the existence of significant differences in the pattern between and within blackberry and raspberry cultivars.

Expression of the Stilbene Synthase (StSy) Gene from Grapevine in Transgenic White Poplar Results in High Accumulation of the Antioxidant Resveratrol Glucosides
TLDR
Despite the presence of piceid, in the experimental conditions no increased resistance against the pathogen Melampsora pulcherrima, which causes rust disease, was observed when in vitro bioassays were performed.

Ripening and genotype control stilbene accumulation in healthy grapes.
TLDR
High resveratrol levels are also accompanied by the up-regulation of genes involved in plant defense and the concomitant underexpression of genes related to the ripening process and to indole alkaloid synthesis.

Relationship of changes in rotundone content during grape ripening and winemaking to manipulation of the 'peppery' character of wine.
TLDR
The results presented in this work provide key knowledge for manipulation of the peppery character of wine in order to optimize the intensity of this characteristic wine aroma.

Metabolite and transcript profiling of berry skin during fruit development elucidates differential regulation between Cabernet Sauvignon and Shiraz cultivars at branching points in the polyphenol…
TLDR
Compared with CS, Shiraz showed higher number of significant correlations between metabolites, which together with the relatively higher expression of flavonoid genes supports the evidence of increased accumulation of coumaroyl anthocyanins in that cultivar.

Differences in the amount and structure of extractable skin and seed tannins amongst red grape varieties
Background and Aims: Red wine is a very rich source of flavanols, consisting of catechins and oligomeric and polymeric proanthocyanidins (PAs). The aim of this study was to investigate the…
