Phytochemical analysis was conducted using high-performance liquid chromatography and liquid chromatography– mass spectrometry, while the antioxidant effect was assessed through a DPPH assay. An- timicrobial action was tested on planktonic cultures and biofilms of Porphyromonas gingivalis, Porphyromonas endodontalis, Parvimonas micra, and Fusobacterium nucleatum. Cytotoxicity was evaluated using mouse macrophages (RAW 264.7), rat fibroblasts (L929), and human keratinocytes (HaCaT). Anti-inflammatory effects were measured by an immunoenzymatic assay (ELISA) on RAW 264.7 cells. Statistical analysis was performed using a one-way ANOVA and Tukey’s test. Phytochemical analysis revealed the presence of phenolic com- pounds and flavonoids. The extract demonstrated a reduction of over 95% in biofilms of P. gingivalis, P. micra, and F. nucleatum within 5 min of treatment. Cell viability (HaCaT) remained above 80%. Antioxidant activity showed an EC50 of 353.43 μg/mL, achieving a 50% reduction in free radicals. A significant decrease in TNF-α (a pro-inflammatory cytokine) and an increase in IL-10 (an anti-inflammatory cytokine) were observed. In conclusion, the extract of G. sylvestre exhibits promising potential as a therapeutic agent for treating anaerobic infections, inflammation, and oxidative stress.PDFen-USArtigos de PeriódicosPlants-Basel10.3390/plants14040497Antimicrobial agentsAnti-inflammatory agentsBiofilmsGram-negative anaerobic cocciMIRANDA, D.
