Resumo

The total content and profile of alkaloids in foliar samples of Annona crassiflora from eight different Brazilian Cerrado regions were investigated. Alkaloids were quantified and identified by GC/FID and GC/MS, respectively. Significant quantitative differences were found in these samples. Total alkaloid concentration varied from 221.1 +/- 17.14 ug/g in Mogi-Guacu (SP) to 2986.89 +/- 367.1 ug/g (dry mass basis) in Brasilia (DF). The alkaloids anonaine, annoretine, romucosine and xylopine were detected at different concentrations across regions. Alkaloid concentration and profile varied in A. crassiflora populations, indicating extensive phenotypic plasticity of these individuals. (C) 2012 Elsevier Ltd. All rights reserved. (AU)
