抄録

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 ^<13>C-^1H long range coupling. In connection with this study, we revised some structures of flavanones using this technique.
