The phenols and prodelphinidins of white clover flowers
TLDR
The 13C-NMR spectra showed that the polymers consisted of only gallocatechin and epigallocatechin monomeric units with the latter being about twice as abundant in the extenders but only slightly more than that in the terminating units.About:

Flavonoids and their glycosides, including anthocyanins
Nigel C. Veitch,Renée J. Grayer +1 more
TL;DR: This review describes more than 600 new examples of naturally occurring flavonoids found either as aglycones or glycosides, comprising flavones, flavonols, chalcones, dihydrochalcones and anthocyanidins.
Journal ArticleDOI
The Arabidopsis TDS4 gene encodes leucoanthocyanidin dioxygenase (LDOX) and is essential for proanthocyanidin synthesis and vacuole development
Sharon Abrahams,Elizabeth Lee,Amanda R. Walker,Gregory J. Tanner,Philip J. Larkin,Anthony R. Ashton +5 more
TL;DR: The seed phenotype of ban tds4 double mutants showed that LDOX precedes BANYULS (BAN) in the PA pathway, confirming recent biochemical characterisation of BAN as an anthocyanin reductase.
Journal ArticleDOI
Flavonoid and phenolic glycosides from Salvia officinalis.
Yinrong Lu,L.Yeap Foo +1 more
TL;DR: Three novel phenolic glycosides cis-p-coumaric acid, luteolin glucuronides and vicenin-2 were identified as new sage constituents.
Journal ArticleDOI
Inhibition of angiotensin converting enzyme (ACE) by flavonoids isolated from Ailanthus excelsa (Roxb) (Simaroubaceae).
Monica Rosa Loizzo,Ataa Said,Rosa Tundis,Khaled Rashed,Giancarlo Statti,Antje Hüfner,Francesco Menichini +6 more
TL;DR: All the flavonoids tested exhibited ACE inhibitory activity, in particular the most active compound was kaempferol‐3‐O‐β‐galactopyranoside with an IC50 value of 260 µm.
Journal ArticleDOI
Determination of isoflavones in red clover and related species by high-performance liquid chromatography combined with ultraviolet and mass spectrometric detection.
TL;DR: All 10 isoflavone aglycones, daidzein, formononetin, genistein, pseudobaptigenin, glycitein, calycosin, prunetin, biochanin A, irilone and pratensein in acidic hydrolyzed extracts were successfully separated within 40 min and quantified individually by UV and MS detectors.

Carbon-13 NMR of flavonoids
TL;DR: Agrawal et al. as mentioned in this paper proposed a method for signal assignment of carbon-13 NMR spectroscopy images of the flavonoid structures and established the aromatic substitution pattern.
Journal ArticleDOI
Complexes of the condensed tannins of sainfoin (Onobrychis viciifolia scop.) with fraction 1 leaf protein and with submaxillary mucoprotein, and their reversal by polyethylene glycol and pH
William T. Jones,James L. Mangan +1 more
TL;DR: In this article, it was shown that fraction 1 protein complexes were stable between pH 3.5 and pH 7.0, but at pH 8.0 only 30% of the protein was released from the complex.
Journal ArticleDOI
The effect of condensed tannins on the site of digestion of amino acids and other nutrients in sheep fed on Lotus corniculatus L.
TL;DR: The presence of tannins in the control group increased net apparent absorption of threonine, valine, isoleucine and lysine, and reduced NEAA absorption by 10%, compared with PEG sheep.
Journal ArticleDOI
The DMACA–HCl Protocol and the Threshold Proanthocyanidin Content for Bloat Safety in Forage Legumes
TL;DR: The threshold PA content for bloat safety in forage legumes was estimated to be 1-5 mg PA g -1 DM, and the DMACA-HCl protocol is recommended for PA detection in low-PA plants because of its higher sensitivity than vanillin-acid protocols.
Journal ArticleDOI
Effects of condensed tannins in Lotus pedunculatus on its nutritive value for sheep. 1. Non-nitrogenous aspects
TL;DR: It is concluded that the CT in Lotus pedunculatus grown under high fertility conditions had little effect on fibre and mineral digestion but the depression in DM intake reduced its nutritive value for sheep.
