Journal ArticleDOI
Studies on the acetaldehyde-induced condensation of (-)-epicatechin and malvidin 3-O-glucoside in a model solution system.
TL;DR: Thioacidolysis of the two isolated anthocyanin-ethyl-flavanol dimeric derivatives showed that AnthocyanIn-ethyl linkage was not sensitive to such reactants, whereas the flavanol-ethyl one was, and flavanol's-ethyl linkages were found to be less sensitive to those involved in flavan-ethyl dimers.
Journal ArticleDOI
Study of the acetaldehyde induced polymerisation of flavan-3-ols by liquid chromatography-ion spray mass spectrometry
TL;DR: In this article, an on-line coupling of liquid chromatography with ion spray mass spectrometry (LC-ISP-MS) was used to identify tannin polymers.
Journal ArticleDOI
Study of the reactions between (+)-catechin and furfural derivatives in the presence or absence of anthocyanins and their implication in food color change.
TL;DR: (+)-catechin was separately incubated with furfural or with 5-(Hydroxymethyl)furfural, and the formation of new oligomeric bridged compounds having flavanol units linked by furfuryl or 5-hydroxymethylfurfural groups was observed, showing thus that the two polyphenols competed in the condensation process.
Journal ArticleDOI
Characterization of Flavonoid Glycosides from Fenugreek (Trigonella foenum-graecum) Crude Seeds by HPLC–DAD–ESI/MS Analysis
TL;DR: The quantitative analysis of the identified compounds showed that the phenolic composition of the studied crude fenugreek seeds was predominantly acylated and non-acylated flavone derivatives with apigenin as the main aglycon.
Journal ArticleDOI
Flavonoids: hemisynthesis, reactivity, characterization and free radical scavenging activity.
TL;DR: An overview of the findings concerning the hemisynthesis, the reactivity and the enzymatic oxidation of some flavonoids and shed light on the mechanisms involved in some of these processes and the structures of the resulting products is shed.
