In order to detect fluctuations in ruminal microbial populations due to forage tannins using 16S ribosomal RNA (rRNA) probes, recovery of intact rRNA is required. The objective of this work was to evaluate the effect of polyethylene glycol (PEG) and polyvinylpirrolidone (PVP) on extraction of bacterial rRNA, in the presence of tannins from tropical legume forages and other sources, that hybridi...
Enological tannins are widely used in the winemaking process either to improve different wine characteristics (color stability, among others) or to compensate for low tannin levels. In this work, the influence of the addition of two different enological tannins, mainly composed of hydrolysable (ellagitannins) and condensed tannins, on the evolution of color and pigment composition of two differ...
Condensed tannins are a major class of plant polyphenols. They play an important part in the colour and taste of foods and beverages. Due to their chemical reactivity, tannins are not stable once extracted from plants. A number of chemical reactions can take place, leading to structural changes of the native structures to give so-called derived tannins and pigments. This paper compares results ...
Introduction Recently it has been shown that flavonoids of polyphenolic compounds such as genistein and daidzein isolated from soyfood exert a therapeutic effect on osteoporosis and that they inhibit osteoclast differentiation [1,2]. Moreover, some flavonoids such as quercetin, kaempferol, and condensed tannins such as (-)-epigallocatechin-gallate (EGCG) derived from vegetables, wine, and green...
