Objective: To evaluate the structural and chemical composition of plant and the antioxidant and antimicrobial activities promoted by hexanic, ethanolic and ethyl acetate fractions obtained from leaves of Conocarpus erectus. Methods: Organic fractions were characterized through UPLC-MS and GC-MS. Antioxidant potential was performed through DPPH and molybdenum phosphate techniques. Antibacterial and antifungal assays were performed in accordance with Clinical and Laboratory Standards Institute protocols. Results: The obtained biomass of Conocarpus erectus leaves showed the high presence of glucose (0.45 g/L), cellulose (28.69%), Na (55.126 μg/L) and K (31.163 μg/L). We identified seven compounds in the hexanic and ethyl acetate fractions, and eight compounds in ethanolic fraction. Moreover, phenolic compounds are prevalent in all organic fractions with values of (10.04 ± 0.24), (221.26 ± 1.84), (340.53 ± 0.84) mg/g GAE to hexanic, ethyl acetate and ethanolic fraction, respectively. Antioxidant results showed a high potential in ethyl acetate fraction (71.82 ± 6.87)% and (10.89 ± 0.05)% in DPPH and molybdenum phosphate techniques, respectively. The ethanolic fraction showed moderate bacteriostatic and bactericidal activity against Staphylococcus aureus and presented a high fungistatic potential for all Candida species tested. Conclusions: Organic fractions obtained from leaves of Conocarpus erectus present antimicrobial and antioxidant properties, and these findings contribute to scientific information for the effectiveness on use of this plant in the development of a phytotherapic compound. |
