Abstract (EN): Ethnopharmacological relevance: Salvia chudaei Batt. & Trab. from Algeria is traditionally used to relieve several dysfunctions, including inflammatory and pain-related situations. Aim of the study: This work aimed to confirm scientifically the referred properties. For that, the phenolic composition and antioxidant activity were evaluated as well as acute toxicity, anti-inflammatory and analgesic effects of different doses of the infusion of S. chudaei aerial parts. Materials and methods: Infusion of aerial parts of S. chudaei was prepared and screened for phenolic composition by generalized methods TPC and TFC then by LCDAD-ESI/MSn. DPPH and FRAP were used to evaluate antioxidant activity. Using mice, acute toxicity, anti-inflammatory by carrageenan-induced paw edema, and analgesic by acetic acid-induced writhing and formalin-induced pain activities were tested. Results: The infusion showed 2018 mg GAE/100g DW of phenolics and 1956 mg ECE/100g DW of flavonoids. Phenolic profile by LC-DAD-ESI/MSn revealed the presence of ten compounds: syringic acid hexoside derivative, kaempferol-O-diglucuronide, kaempferol-O-deoxyhexoside-hexoside, kaempferol-O-glucuronide, apigenin-O-diglucuronide, caffeic acid, 4-O-caffeoylquinic acid, eriodictyol-O-glucuronide, rosmarinic acid hexoside, and rosmarinic acid. This acid was the major compound representing 54% of the total content of the identified compounds and an absolute content of 18 mg/g of extract. Additionally, the infusion exhibited a good antioxidant activity (DPPH: 81 mu mol TE/g DW, FRAP: 438 mu mol FSE/g DW). By oral administration to mice, the infusion showed a significant (p<0.05) dose-dependent reduction of carrageenan-induced inflammation and inhibition of formalin-induced pain (late and early phase) and acetic acid-induced writhing compared with the control. On the other hand, infusion up to 8 g/kg b.w. showed no signs of toxicity or mortality. Conclusion: This study reveals, for the first time, that the infusion of the aerial parts of S. chudaei is not toxic in a single dose and has remarkable antioxidant, antiinflammatory, and analgesic activities, supporting the use of this species in folk medicine.
