Abstract

Six known furanoquinoline alkaloids have been isolated from the wood and trunk bark of Comptonella sessilifoliola (Guillaumin) Hartley (Rutaceae). 2D NMR experiments gave the assignment of all the signals for both 1H- and 13C-NMR spectra. Pteleine and kokusaginine were used as models. The two-dimensional carbon-proton correlation experiments, performed for the first time on furanoquinoline alkaloids, led us to correct 13C-NMR assignments previously described in the literature.
