Abstrakt: Ethnopharmacological Relevance: Remijia ferruginea DC. (Rubiaceae) (syn. Cinchona ferruginea A.St.-Hil.) is used in traditional medicine for the treatment of wounds, fever and malaria.
Aim: This study investigated in vitro the proliferative and antioxidant effects of hydroalcoholic extract of leaves of R. ferruginea (HERF) and in vivo the healing effect of ointment based on HERF.
Materials and Methods: The plant extract was characterized by liquid chromatography/mass spectrometry. Cell proliferation assays and in vitro antioxidant activity were performed. In in vivo assays, wound contraction ax was evaluated, as well as histological analyzes such as cellularity, proportion of blood vessels and collagen type I and III index. In addition, analyzes of the antioxidant enzymes SOD, CAT and GST were performed.
Results: Our results showed in the chromatographic analysis that catechin, rutin and quercetin were the main phenolic compounds in the plant extract and may be responsible for the antioxidant and proliferative effects (p < 0.05). In addition, these compounds were found in higher concentration in leaves collected in spring. The ointment containing HERF was able to modulate tissue morphology, increasing cell proliferation, blood vessels, being able to stimulate the production of collagen fibers type I and III, (p < 0.05) contributing to scar tissue maturation and resistance.
Conclusion: Our findings indicated that the three doses of HERF tested (1%, 3% and 5%) can modulate the skin repair process, but the best effects were observed after exposure to the highest dose.
