Metabolites Are Key to Understanding Health Effects of Wine Polyphenolics

Metabolites are key to understanding health effects of wine polyphenolics.

Phenolic compounds in grapes and wine are grouped within the following major classes: stilbenes, phenolic acids, ellagitannins, flavan-3-ols, anthocyanins, flavonols, and proanthocyanidins. Consumption of foods containing phenolic substances has been linked to beneficial effects toward chronic diseases such as coronary heart disease and colorectal cancer. However, such correlations need to be s...

Grape and Wine Metabolites: Biotechnological Approaches to Improve Wine Quality

Grape metabolites can be affected by many extrinsic and intrinsic factors, such as grape variety, ripening stage, growing regions, vineyard management practices, and edaphoclimatic conditions. However, there is still much about the in vivo formation of grape metabolites that need to be investigated. The winemaking process also can create distinct wines. Nowadays, wine fermentations are driven m...

Social Relationships Are Key to Health, and to Health Policy

Evidence from observational studies has documented the association between social relationships and beneficial effects on health outcomes, such as mortality [1]. However, the precise size of this effect, and of which aspects that form part of social relationships are most strongly linked with positive outcomes, remain unclear. Now, a systematic review and meta-analysis of the literature [2] she...

From functional food to medicinal product: Systematic approach in analysis of polyphenolics from propolis and wine

In the last decade we have been working on standardization of propolis extract and determination of active constituents of wine those are rich in polyphenolics and have nutritional as well as therapeutic value. Here we are summarizing our results and providing overview on systematic approach how to analyse natural products rich in flavonoids and phenolic acids.Chromatographic methods (thin laye...
