However, with the advent in recent years of pulsed NMR and Fourier Transform (FT) analysis, 13 C-NMR spectroscopy has become more readily available.

Book Title The Flavonoids Book Subtitle Advances in Research Authors. Harborne. 13 C-NMR spectra of hydroxylated flavones and flavonols are presented for the first time. Analyses of the spectra are derived by consideration of a series of acetophenones, cinnamic acids, flavones and flavonols of increasing oxygenation pattern.

13 C NMR spectra for a variety of flavonoid glycosidcs are presented and analysed. Evidence is presented which demonstrates that 13 C NMR spectroscopy is a valuable technique for distinguishing the sites of methylation, glycosylation and acylation in flavonoid glycoiides, and in some cases the nature and sites of specific sugars and acyl groups.

Utilizing the distinct HMBC cross-peak patterns of lower-field range (LFR; – ppm) hydroxyl singlets, presented NMR methodology characterizes flavonoid metabolomes both qualitatively and quantitatively. It enables simultaneous classification of the structural types of 5-OH flavonoids and biogenetically related 2′-OH chalcones, as well as quantification of individual metabolites.
