Abstract

The genus Combretum (Combretaceae) includes several species traditionally used in folk medicine and reported as sources of bioactive compounds with anti-inflammatory potential. However, the species Combretum rupicola remains poorly studied. This study aimed to extract chemical constituents from C. rupicola leaves, qualitatively identify the presence of flavonoids, and evaluate, through in silico simulations, the interaction of characteristic compounds from the family with inflammatory molecular targets. Leaves were collected at IFTO–Araguatins Campus, processed, extracted by ultrasound using an acetonitrile/methanol (80:20) solution, and the extract was subsequently lyophilized. Phytochemical screening confirmed the presence of flavonoids, especially quercitrin. For the in silico study, ligands described in Combretaceae were selected, including quercitrin, kaempferol, betulinic acid, combretol, rhamnazin, and combretastatin A-4. The proteins COX-2, NLRP3, P38, TNF, and CXCR4 were used as targets, and docking experiments were carried out using AutoDock 4.2. The results showed favorable interactions between ligands and the active sites of the proteins, with emphasis on quercitrin and combretastatin, which displayed binding energies comparable to or higher than reference inhibitors. These findings suggest that C. rupicola is a promising source of compounds with anti-inflammatory potential, supporting further experimental investigations.
