In vivo assessment of anti-inflammatory and antioxidant activities of Phlomis crinita polyphenols
The leaves of Phlomis crinita are traditionally used in Algerian medicine for the treatment of pain and inflammatory conditions. In order to find a potential application for this native species, the anti-inflammatory and antioxidant effects were investigated on various in vivo experimental models, and the total phenolic compounds and flavonoid contents were determined. The carrageenan-induced paw edema method was used to evaluate the anti-inflammatory activity of the extract in vivo, while the in vivo antioxidant effect was assessed by estimating oxidative stress parameters (MDA, CAT, and SOD). Phytochemical screening revealed the presence of substances with high therapeutic values. In vivo anti-inflammatory studies show that plant extract has a significant and dose-dependent impact on the inhibition of edema formation. The maximum percentage inhibition value was 87.79% after 4 h at a concentration of 500 mg/kg. Moreover, the administration of the extract significantly enhanced the activities of antioxidant enzymes in the livers of mice. It significantly (p ˂ 0.05) increased CAT and SOD activities and significantly (p ˂ 0.05) decreased the MDA level activity, compared to the control inflammatory group. Our findings support that Phlomis crinita can be considered as a promising source of therapeutic bioactive compounds.
