Phenolic Profiling, In Vitro Antiglycation, Antioxidant Activities, and Antidiabetic Effect of Algerian Trigonella Foenum-Graecum L. in Rats Administered a β-Cell Toxicant.

This study sought to quantitatively assess individual and total polyphenols, mineral composition, antioxidant and antiglycation activities of Algerian fenugreek seeds (AFS) as well as the antidiabetic effect of its supplementation on streptozotocin-induced diabetic rats. Forty rats were divided into four groups (i) non diabetic rats, (ii) non diabetic rats +10 % AFS, (iii) diabetic rats, (iv) diabetic rats +10 % AFS. Flame-SAA analysis revealed a rich content in micro-elements, HPLC DAD-FLD analysis revealed twenty components with rutin and ferulic acid being the major compounds in AFS hydro-methanolic extract while spectrophotometric assays scrutinized moderate contents in total phenolics and flavonoids.
