1. The chemical shifts and spin-spin coupling constants of the protons of the alkaloid haplophyllidine in 12 solvents have been studied.

2. It has been shown that in deuteropyridine the signals are located in a weaker field than in deuterobenzene.

3. The protons of the furan ring undergo the strongest influence of solvents.
