TL;DR: Data suggested that the presence of galloyl moieties within the structure was required for enhancement of pancreatic lipase inhibition, and it was well-known that flavan-3-ols are polymerized by polyphenol oxidase and/or heating in a manufacturing process of oolong tea.

TL;DR: This work down-regulated the endogenous dihydroflavonol 4-reductase (DFR) gene and overexpressed the Irisxhollandica DFR gene in addition to the viola F3'5'H gene in a rose cultivar, resulting in the accumulation of a high percentage of delphinidin and a novel bluish flower color.

TL;DR: Chalcone 4'-O-glucosyltransferase (4'CGT) is essential for aurone biosynthesis and yellow coloration in vivo, and the findings herein open the way to engineering yellow flowers for major ornamental species lacking this color variant.

TL;DR: It is concluded that (+)-catechin 5-O-beta-glucuronide and (-)-epicatechin 5 -O- beta-glUCuronide are the biologically active in vivo structures of the ingested polyphenolic antioxidants.

TL;DR: This is the first report of the gene isolation of a B-ring-specific glucosyltransferase of anthocyanins, which paves the way to modification of flower color by production of blue anthocianins.
