Extensive colour difference calculations (CIELAB and CMC models for CIE D 65 /10°, Ill./Obs.) were applied to the colorimetric coordinates previously gathered on 224 pure or co-pigmented (by rutin) solutions of cyanin at pH between 2.5 and 5.5. CIEL

Spectral measurements (380–780 nm) were performed on 224 model solutions of cyanin co-pigmented by the flavonol rutin at pH between 2.5 and 5.5. The colour of the solutions was expressed as colorimetric co-ordinates in the CIELAB scale using the L

This method is based on a spectral curve recorded and considered over the full range of visible light and a subsequent colorimetric specification (CIELAB system, L ∗ , C ∗ , h notation for the D65/10 ° illuminant/observer condition) using the th

From a series of wild accessions of Centaurea montana displaying markedly dissimilar flavonoid phenotypes (notably C-glycosides vs. O -glycosides) different experimental breeding operations were performed. Variation was observed in individual glycosi

Individuals of Centaurea triumfetti (Compositae) from two distant origins (Switzerland and Yugoslavia) were surveyed for their flavonoid glycosidic patterns. Diversity in the distribution of the 27 flavonoids detected mainly concerned 6-C-mono-glucos

Individuals of Centaurea montana (Compositae) originating from two types of alpine plant community—tall grass prairies under Larix (Adenostylion) and high-altitude manured meadows (Triseto—Polygonion)-were investigated for their flavonoid glycosi

Flowers of the rose cultivar Rhapsody in Blue display unusual colors, changing as they age, from a vivid red-purple to a lighter and duller purple, which are based on tonalities corresponding to hue angles between 340 and 320 degrees in the CIELAB sc

This work presents a further step in the analysis of flavonoid aglycones excreted in the leaves of Alnus glutinosa as an aid to the characterization of natural specimens of this species. The stability in the flavonoid pattern of specimens growing und
