The Minor Flavonoids

1982
It is the purpose of this chapter to discuss the five remaining flavonoid structural types, here collectively known as the minor flavonoids, chalcones, aurones, dihydrochalcones, flavanones and dihydroflavonols. In order to orientate the reader it should be mentioned that chalcones, aurones and dihydrochalcones were discussed in Chapter 9 of The ...

The flavonoids of Allium neapolitanum

Phytochemistry, 1997
An investigation of the extracts from Allium neapolitanum has led to the isolation of 13 flavonoid glycosides, based on kaempferol, quercetin and isorhamnetin. Four of them are new compounds and have been identified as: kaempferol 3-O-[[2-O-alpha-L-rhamnopyranosyl-4-O-beta-D-glucopyranosyl]-beta-D- glucopyranoside]], isorhamnetin 3-O-[[2-O-alpha-L ...

Flavonoide, XXXII. Oxidative Umwandlungen schwefelhaltiger Flavonoide

Justus Liebigs Annalen der Chemie, 1977
AbstractDurch Oxidation des Flaventhions (2a) und des 1‐Thioflaventhions (2b) mit äquimolekularer Menge Monoperoxyphthalsäure werden die entsprechenden Flaventhionoxide 3a und 3b gewonnen. Aus diesen entstehen durch weitere Oxidation Flavon (1a) bzw. 1‐Thioflavon (1b). Die Verbindungen 1a und 1b erhält man auch durch Reaktion von 2a bzw.

Properties and applications of flavonoid metal complexes

, 2015
Flavonoids are widely occurring polyphenol compounds of plant origin with multiple biological and chemical activities. Due to the presence of carbonyl and hydroxyl groups they can coordinate metal ions and form complexes.

Antioxidative Properties of Flavonoids

Current Organic Chemistry, 2011
Evidence accumulates that a family of plant compounds, known as flavonoids, can prevent or slow down the progression of cardiovascular diseases, cancer, inflammatory and neurodegenerative diseases. Flavonoids are considered beneficial, this is often attributed to their powerful antioxidant properties.
