Flavonoid p-coumaroylglucosides and 8-hydroxyflavone allosylglucosides in some labiatae
TLDR
Flavonoid p -coumaroylglucosides are valuable markers for chemotaxonomic studies and are universally present in the subgenus Marrubiastrum of Sideritis and in section Betonica of genus Stachys, while 8-hydroxyflavone 7-allosylglucOSides accumulate in the other Siderococcus species.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
Characterization of the interglycosidic linkage in di-, tri-, tetra- and pentaglycosylated flavonoids and differentiation of positional isomers by liquid chromatography/electrospray ionization tandem mass spectrometry.
TL;DR: In tetra- and pentaglycosylated flavonoids, the ions that characterize the (1-->2) interglucosidic linkage formed by intermediate fragmentation of the oligosacharide residues (sophorosides and sophorotriosides) are found in much higher relative abundance in MS3 than in MS2 experiments, where they are almost not detected.

A chemotaxonomic study of flavonoids from european teucrium species
TL;DR: The chemical results are correlated with sectional classification and usefully indicate that at least one taxon, T. compactum, is misplaced within the genus Teucrium.
