Abstract
1H and 13C NMR spectra are documented for the novel flavone-6,8-di-C-glycosides isolated from the liverwort, Apometzgeria pubescens. The existence of rotational isomerism evident from these spectra is shown to be general for 8-C-monohexosylflavones and of possible diagnostic value.Keywords
