Cerrado biome represents an area with great biodiversity. Some of its plants have
significant ethnopharmacological uses, with specific purposes. Croton urucurana Baill., for instance,
was previously acknowledged for its anti-hemorrhagic, anti-inflammatory, antiseptic, healing,
and potentially antifungal and entomopathogenic actions. Nevertheless, the compounds supporting
these empirical applications are still unknown. Accordingly, this work was designed to achieve
a complete characterization of the phenolic profile of di erent botanical tissues obtained from
C. urucurana, and also to verify how di erent operational conditions (di erent drying temperatures
and extraction conditions) a ect that profile. All samples were further characterized by
HPLC–DAD–ESI/MSn, and results were compared by advanced chemometric tools. In general,
the drying temperatures that maximize the extraction yield of specific individual phenolic
compounds were established. Likewise, it was possible to verify that samples extracted with
the hydroethanolic solution allowed higher phenolic yields, either in individual compounds
(except (epi)catechin-di-O-gallate) or total phenolics. The identification of the best operational
conditions and phenolic profiles associated with each C. urucurana botanical part contributes to
enabling their use in food or pharmaceutical-related applications.
