Abstract

A new pyrrolizidine alkaloid, named crotavitelin, was isolated from fruits of Crotalaria vitellina, Fabaceae (Papilionoideae). The structure was established by spectroscopic techniques such as one-dimensional and two-dimensional NMR, IR, and MS.

Keywords: 13C NMR; 1H NMR; Crotalaria vitellina; pyrrolizidine alkaloids.
