DIVERSIDAD GENÉTICA Y MEJORAMIENTO DE PLANTAS MEDICINALES= Medicinal plants and improvement of medicinal herbs:

Gas chromatog.-mass spectrometry anal. of seeds from 28 species of Crotalaria from Brazil (sections Calycinae, Crotalaria, Chrysocalycinae and Hedriocarpae) showed that pyrrolizidine alkaloids (PAs) are important as chemotaxonomic markers at the infrageneric level.  The sections Calycinae and Crotalaria were characterized by 11-membered macrocyclic monocrotaline-type PAs.  In the section Chrysocalycinae, a single species in the subsection Incanae, C. incana, showed integerrimine, a 12-membered macrocyclic senecionine-type, as main PA.  The group close to the subsection Stipulosae (C. micans and C. maypurensis) showed distinctive PA patterns: C. micans presented mainly the 12-membered macrocyclic integerrimine, and C. maypurensis the unusual 7-hydroxy-1-methylene-8-pyrrolizidine.  In the group close to the subsection Glaucae, the PAs with otonecine as the necine base were the main alkaloids, except in C. rufipila which showed an assamicadine-like PA (monocrotaline-type).  The section Hedriocarpae showed main 12-membered macrocyclic senecionine-type PAs.
