Resumen:
Quinolizidine alkaloids were surveyed using gas chromatography (GC) and combined mass spectroscopy (MS) in bark or leaves of eleven species of Ormosia Jackson as well as in Clathrotropis macrocarpa Ducke from tropical forests in Latin America. A list of detected alkaloids, with their MS fragmentation patterns and GC retention indices, is given, as are the distribution of alkaloids among the samples and their detected concentrations. Alkaloid diversity in Ormosia was high, and the taxonomic distribution of specific alkaloids was not congruent with morphological taxonomic criteria: Of 143 alkaloids apparent in 14 samples, 65 were observed in only one sample, and no single alkaloid was common to all samples. Within a species, alkaloid concentrations were inconsistent and therefore cannot be used as a taxonomic character. This was shown for leaf alkaloid concentrations of two neighboring conspecific trees in the same habitat. © 1994 The New York Botanical Garden.
