Carbon-13 NMR Spectroscopy of Flavonoids
TL;DR: For example, Ternai et al. as mentioned in this paper used Fourier Transform (FT) NMR spectroscopy of 13C-NMR for the structure elucidation of flavonoids and their glycosides.
Book ChapterDOI
Flavones and Flavonols
TL;DR: In this paper, all references to the occurrence of flavone and flavonol aglycones which have appeared from 1975 to 1980, and also include such earlier references as were overlooked in the relevant chapters of The Flavonoids' (1975).

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.

Antimutagens in gaiyou (Artemisia argyi Levl. et Vant.).
TL;DR: The methanol extract prepared from aerial parts of this plant strongly reduced the mutagenicity of 3-amino-1-methyl-5H-pyrido[4,3-b]indole (Trp-P-2), when Salmonella typhimurium TA98 was used in the presence of the rat liver microsomal fraction.

The Constituents of Osmunda spp. II. : A New Flavonol Glycoside of Osmunda asiatica
TL;DR: A novel flavonol glycoside, mp 182-184°, named asiaticalin (I) was isolated from the fresh trophophyll of Osmunda asiatica OHWI (Osmundaceae) as discussed by the authors.
Journal ArticleDOI
Iridoid allosides from Viburnum opulus
TL;DR: In this paper, Opulus iridoid glycoside esters were isolated from foliage of Viburnum opulus (Caprifoliaceae) and the structures were elucidated by 1 H and 13 C-NMR spectroscopy and by cleavage of the glycosidic linkage with boron trifluoride etherate in acetic anhydride.
Journal ArticleDOI
Iridoid mono- and di-glycosides in Mentzelia
TL;DR: In this article, eight species of Mentzelia (Loasaceae) have been investigated for iridoid glycosides and several novel compounds have been isolated and characterized by chemical and spectroscopic means.
Journal ArticleDOI
Flavonoids in Parahebe and Veronica: a chemosystematic study
TL;DR: Most species of both genera have a distinctive pattern of flavonoid glycosides in their leaves which can be used for identification, and here the variety in flavone profiles corresponds to the pattern of morphological and geographic variation within this taxon.

Proton and carbon-13 nuclear magnetic resonance studies of flavone and deuterated analogs
TL;DR: In this article, the proton noise decoupled 13 C spectra of flavone, 5,6,7,8-tetradeuteroflavone, 2′,3′,4′,5′,6′-pentadeuter-of-lavone and 4′-brom oflavone were compared.
