Phytochemical analysis, antioxidant, and antihyperlipidemic activities of Teucrium takoumitense

Objective: The main purpose of the present work was to determine the chemical composition, safety, and antiox-idant and antihyperlipidemic activities of an aqueous extract of Teucrium takoumitense.Methods: Phytochemical analysis (total phenolic, total flavonoid, and total hydroxycinnamic acid contents), antioxidant activity (ferric-reducing antioxidant power, 2,2MODIFIER LETTER PRIME-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid, 2,2-diphenyl-1-picrylhydrazil, and total antioxidant ca-pacity tests), acute toxicity, and antihyperlipidemic ac-tivity were evaluated according to established models. In addition, the phytochemical profile was determined by methylation followed by gas chromatography-mass spectrometry (GC/MS).Results: The aqueous extract of T. takoumitense had a high content of total polyphenols (87.01 & PLUSMN; 0.31 mg gallic acid equivalent (GAE)/g extract) and hydroxycinnamic acid (2.28 & PLUSMN; 0.1 g/100 g Powdered Material) and a low content of total flavonoids (2.99 & PLUSMN; 0.16 mg GAE/g extract). In addition, the extract demonstrated remarkable antioxidant activity (DPPH IC50 = 76.67 & PLUSMN; 0.56 & mu;g/mL, ABTS IC50 = 89.65 & PLUSMN; 0.27 & mu;g/mL, FRAP EC50 = 296.32 & PLUSMN; 0.86 & mu;g/ mL, TAC value = 43 & PLUSMN; 0.27 mg EAA/g extract). The main compounds were identified as benzene, (hexyloxy)(19.32%), 2,6a-methano-6aH-indeno[4,5-b]oxirene, octahedro-(1a.alpha., 2.beta., 3a.alpha., 6a.beta., 6b.alpha.)(32.42%), D-fucose (5.47%), 5-hydroxymethylfurfural (5.47%) and guaiacol (3.19%). The LD50 was estimated to be between 500 and 2000 mg/kg. Furthermore, at 500 and 250 mg/kg, the aqueous extract of T. takoumitense exhibited good antihyperlipidemic activity in vivo.Conclusion: T. takoumitense extract has significant pharmacological potential and a varied chemical composition.
