Abstract

C-6 or C-8 substituted flavanones were determined by methods of chemical and/or 1H-NMR spectral analysis. We report a very convenient method for determining the substituted position of these flavanones using 13C-1H long range coupling. In connection with this study, we revised some structures of flavanones using this technique.
