Abstract
Chronic disease inflammation requires safe complementary treatments. The pericarp of Passiflora tripartita var. mollissima (PTM) contains potential anti-inflammatory metabolites. This study aimed to evaluate the bioactive components, antioxidant capacity, and anti-inflammatory effects of PTM extracts at two ripening stages. The bioactive compounds in the hydrophilic and lipophilic extracts of mature and green pericarps were identified by GC-MS and UV–VIS, while the antioxidant capacity was measured by free radical reduction. Anti-inflammatory effects were tested using a rat paw edema model with carrageenan-induced edema, indomethacin, or PTM extracts (100, 250, and 500 mg/kg). The effect of mature hydrophilic extract was further evaluated in an air pouch model, where rats received the placebo, carrageenan, indomethacin, or the extract (500 and 1000 mg/kg). Leukocytes, cytokines, and markers of oxidative stress were evaluated. The results showed the presence of organic compounds, total phenols, and flavonoids. The mature hydrophilic extract exhibited the highest antioxidant activity. At 500 mg/kg, it reduced edema, leukocyte migration, and levels of IL-1β, IL-6, and TNF-α while managing oxidative stress and preventing histological damage. In conclusion, PTM contains bioactive compounds with potential pharmacological properties. The hydrophilic extract of the mature pericarp, at a dose of 500 mg/kg, exhibits an enhanced antioxidant and anti-inflammatory effect.
