Isabel Rivero-Cruz,Laura Acevedo,José Antonio Chamizo Guerrero,Sergio F. Martínez,Robert Bye,Rogelio Pereda-Miranda,Scott G. Franzblau,Barbara N. Timmermann,Rachel Mata +8 more
TL;DR: Although the tested compounds showed moderate antimycobacterial activity, their presence in the analysed species provides the rationale for their traditional use in the treatment of tuberculosis.

Nouvelles C-glycosylflavones extraites de Spergularia rubra
Marie-Louise Bouillant,F.Ferrered de Arce,Jean Favre-Bonvin,Jean Chopin,Anne Zoll,G. Mathieu +5 more
TL;DR: Three 6,8-di-C-glucosylflavones were isolated from the whole plant of Spergularia rubra and two new compounds, 7,2″-di -di-O-β- d -glucopyranosyl-6 -C-α- l -arabinopyranoylapigenin and 6-C -α-L-arabinopoline (isomollupentin) were characterized.
Journal ArticleDOI
Geographic races of conocephalum (marchantiales) as defined by flavonoid chemistry
TL;DR: An earlier proposal that Conocephalum conicum may exist as a group of geographic races is supported by a more extensive survey of the flavonoid glycosides isolated from samples across its Northern Hemisphere distribution.

Cytotoxic saponins and other natural products from flowering tops of Narthecium ossifragum L.
Andrea Estefanía Carpinteyro Díaz,Lars Herfindal,Bendik Auran Rathe,Kristine Yttersian Sletta,Anni Vedeler,Svein Haavik,Torgils Fossen +6 more
TL;DR: The saponins are the toxicants mainly responsible for kidney damage observed in cattle after ingestion of N. ossifragum, with proportionally increasing cytotoxicity with increasing number of glycosyl substituents.
Journal ArticleDOI
Aromatic compounds and triterpenoidal saponins fromClematis koreana var.umbrosa
TL;DR: In this paper, the methanolic extract of aerial parts of Clematis koreana var.umbrosa was used to extract triterpenoidal saponins.

Journal ArticleDOI
Structural determination of C-glycosylflavones by mass spectrometry of their permethyl ethers
TL;DR: In this article, the structure of dissymmetrical 6,8-di-C -glycosylflavones is discussed and the natures of the sugar in both the 6 and 8 positions can be determined.
Journal ArticleDOI
Flavonoid methyl ethers on the external leaf surface of Larrea tridentata and L. Divaricata
TL;DR: Except for a few isolated 2 n populations which exhibited minor differences, a single chemical type was observed for all three ploidy levels in the North American L. tridentata suggesting an autoploid origin for the tetraploid and hexaploid races.
Journal ArticleDOI
Flavonoids from the Moss Mnium affine Bland
TL;DR: Eight different flavone C-glycosides from Mnium affine were tentatively identified by chromatography and spectroscopy as well as unidentified flavonoids found in M. arizonicum.
