| Popis: | Protium ovatum Eng. Burseraceae is an endemic species in Brazil used in traditional medicine. This study investigated the chemical variation and the in vitro antioxidant and antimicrobial properties of dichloromethane soluble fraction of hydrolate (DSFH) from leaves of P. ovatum collected from five different vegetation physiognomies within the Cerrado Goiano. The region was characterized based on the DSFH chemical composition by gas chromatography coupled to mass spectrometry (GC-MS) analysis. Principal component analysis (PCA) and hierarchical cluster analysis (HCA) were performed to compare the different DSFHs from five Savannah regions in Brazil. The DSFHs from the Cerrado stricto sensu (CSS), Mata de Galeria (MG) and Cerradão (C) regions were grouped in the negative part of PC1, showing high similarity. Samples from the C and MG regions showed antioxidant activity of IC50 = 0.98 and 0.78 mg mL-1, respectively, and 0.250 mg mL-1 of butylated hydroxytoluene (positive control). DSFH from different regions exhibited antifungal activity against Candida albicans. The results show that the chemical composition and the biological activity of DSFHs can be affected according to the area of collection. |
