Salvia tiliifolia Vahl (Lamiaceae) is used for the empirical treatment of pain and inflammation. The diterpenoid tilifodiolide (TFD) was isolated from Salvia tiliifolia. The in vitro anti‐inflammatory effects of TFD (0.1–200 µM) were assessed using murine macrophages stimulated with LPS and estimating the levels of pro‐inflammatory mediators for 48 h. The in vivo anti‐inflammatory activity of TFD was assessed using the carrageenan‐induced paw edema test for 6 h. The antinociceptive effects of TFD were evaluated using the formalin test and the acetic acid induced‐writhing test. The effects of TFD on locomotor activity were assessed using the open field test and the rotarod test. TFD inhibited the production of TNF‐α (IC50 = 5.66 µM) and IL‐6 (IC50 = 1.21 µM) in macrophages. TFD (200 mg/kg) showed anti‐inflammatory effects with similar activity compared to 10 mg/kg indomethacin. The administration of TFD induced antinociception in the phase 1 (ED50 = 48.2 mg/kg) and the phase 2 (ED50 = 28.9 mg/kg) of the formalin test. In the acetic acid assay, TFD showed antinociceptive effects (ED50 = 32.3 mg/kg) with similar potency compared to naproxen (ED50 = 36.2 mg/kg). In the presence of different inhibitors in the acetic acid assay, only the co‐administration of TFD and naloxone reverted the antinociceptive activity shown by TFD alone. TFD did not affect locomotor activity in mice. TFD exerts in vitro and in vivo anti‐inflammatory activity and in vivo antinociceptive effects.
