Abstract: 13C chemical shifts of 14 kinds of β Naphthoflavoncs and β-Naphthoflavonones have been studied. The chemical shift changes of these compounds are almost identical with those of flavones. All carbon chemical shifts have been assigned on the basis of COSY, HETCOR, HETCOLOC and PBB, DEPT, QUAT experiments

Key words: β-Naphthoflavones, β-Naphthoflavonones, 13C NMR, 2D NMR
