Abstract: Emperical formulas were set up according to the additive theory of chemical shift in this paper. The chemical shifts of 9 quinoline alkaloids were calculated using the proposed emperical formula. Calculated and experimental shifts are in excellent agreement. The chemical shifts of 32 compounds were predicted in addition.

Key words: Quinoline alkaloids, 13C NMR, Shift rule
