Flavonoids appear to be some of the predominant constituents in noni leaves. As flavonoids exist mostly in the forms of glycosides or polymers, degradation to corresponding metabolites is usually needed for bio-absorption. This study investigates the effects of thermal treatment (non-aqueous roasting)...

flavonoidscolonmicrobial degradationpigsThe present study investigated the microbial degradation of the plant flavonol quercetin and its naturally occurring glycosides isoquercitrin and rutin in the porcine hindgut. The experiments were carried out with the semicontinuous colon-simulation technique. The fluid ...
Bilberry (Vaccinium myrtillus) represents one of the richest flavonoid sources among plants. Flavonoids play variable, species-dependent roles in plant defences. In bilberry, flavonoid metabolism is activated in response to solar radiation but not against mechanical injury. In this paper, the defence ...
In this work, the degradation by ozonation of flavonoids and phenolic acids were studied using two compounds: rutin and caffeic acid. Ozonation was efficient and was monitored by liquid chromatography, UV scanning and direct infusion electrospray ionization mass spectrometry. From the collected data, ...
As intestinal metabolism strongly influences the bioavailability of flavonoids, this study investigated the microbial deconjugation and degradation of the most common flavan-3-ols using the pig cecum in vitro model system developed in the authors' group. The microbial degradation of (+)-/(-)-catechin...
To the best of our knowledge, this is the first report showing that Hb has the catalytic ability to convert naturally occurring bioactive compounds, such as dietary flavonoids, to the corresponding conjugates in the presence of thiol donors or CoA....

Silver nanoparticles (FAgNPs) were synthesized using flavonoids within 10 min. • The FAgNPs morphology is spherical and well-dispersed with a size range of 15–20 nm. • The FAgNPs verified the strong inhibition against A. faecalis and A. niger. • The FAgNPs showed good photocata...
