Curcumin, a polyphenolic constituent isolated from Curcuma longa L. Zingiberaceae (Fig. 6), and a methanol extract of the dried powdered turmeric rhizome were both active against 19 strains of HP, including five CagA- - strains. The MIC range was 6.25-50 /tg/mL. In addition, a red wine Vitis vinifera) and resveratrol, inhibited the growth of HP... 

White wines were uniformly low in HA protein, while red wines were quite variable (Siebert et al., 1996b). Vitis vinifera white wines had very low levels of HA polyphenols, while Vitis labrusca white wines had higher and vinifera-labrusca hybrids had intermediate levels (Siebert et al., 1996b). All red wines had high levels of HA polyphenols, and most had low levels of HA protein the two exceptions were both hybrids.

Over the last 100 years, the grapevine Vitis vinifera L. (Vitaceae), the primary source of wine, has been the subject of numerous chemical studies. While stilbenoids are found in a number of plant species [19], grapes and related products are the most significant dietary source of these substances [20]. Stilbenoids are non-flavonoid polyphenols with an essential structural skeleton of two aromatic rings joined by an ethylene bridge (C6-C2-C6). Over 1,000 stilbenoids have been...

However, little research has been conducted toward the exploitation of lignin from vine shoots for polyphenol production. Volf et al. [223] have proposed a method for polyphenols, which are separated from wood and stems of Vitis sp. by global alkaline extraction, and developed a mathematical model for predicting the amount of polyphenols extracted under specific operational conditions with a view to transfer their method to a pilot or even industrial scale.
