Resumo
This work describes the potential of chemometric analyses applied to 1H high-resolution magic
angle spinning nuclear magnetic resonance (1H HR-MAS NMR) data for the chemotaxonomic
investigation of Hancornia speciosa (Apocynaceae) varieties. This plant, popularly known as
mangaba, has a complex morphological differentiation and thus chemical analyses can be used
for their taxonomic classification. In comparison to traditional techniques, 1H HR-MAS NMR
allied with chemometrics provided a simple and low cost method for chemotaxonomy. Leaves of
four varieties of H. speciosa from a common garden experiment was studied and demonstrated
that H. speciosa var. speciosa differs from others due to its specific metabolic profile, and var.
pubescens was discriminated based on its high phenolic compound content. The distinction between
the latter variety and gardineri is important once it allows for the selection of samples with greater
commercial value, once they produce the largest and heaviest fruits.
