## Abstract The ^13^C NMR chemical shifts of nine acetoxyxanthones are reported and identified. The acetoxy substituent effects have been evaluated and the corresponding shift increments proposed.

The structural elucidation of 24 xanthones with di †erent substitution patterns was performed by spectroscopic methods, namely 2D NMR techniques, such as correlation spectroscopy (COSY), nuclear Overhauser e †ect (NOE), heteronuclear correlation (HETCOR) and a 1D NMR technique, selective insensitive
## Abstract A procedure for developing ^13^C NMR chemical shift additivity rules for all 136 polymethoxyxanthones and all 136 polyacetoxyxanthones, based on multiple linear regression analysis, is reported. The influence of steric interactions between the substituents on the chemical shifts of the
