Resumen:
Quinolizidine alkaloids were surveyed in 22 plant samples, representing nine Ormosia species and up to five different plant parts per species, using combined gas chromatography and mass spectroscopy. The detected alkaloids were classified into 40 structural types. There was a remarkable degree of dissimilarity of alkaloid-type profiles between any two plant samples, including those obtained from the same species and even from a single tree. The similarity of alkaloid-type profiles among the studied samples varied between 0% and 79% (Jaccard similarity coefficient). Of chemotaxonomic interest was the finding of acosmine in O. isthmensis, which previously had been reported only from the related genus Acosmium. Furthermore, the alkaloid-type profile of O. panamensis seeds was distinct from that of all other samples, supporting the hypothesis that this species is only distantly related to the other Latin American Ormosia species.
