Abstrakt: Sorghum is a vital cereal source that has various phenolic compounds and potential health-promoting benefits. This study evaluated the phenolic content, antioxidant and anti-obesity effects of sorghum extract (SE) prepared using three solvent systems: 50% (SE50), 80% (SE80), and 100% (SE100) ethanol. The results showed that SE50 exhibited the highest total polyphenol and flavonoid content among the sorghum extracts using different ethanol concentrations as extraction solvents. In addition, SE50 showed significantly higher antioxidant capacity than the other extracts. Interestingly, SE50 significantly inhibited lipid accumulation in 3T3-L1 adipocytes; however, SE80 and SE100 had no beneficial effects. Moreover, SE50 significantly downregulated the mRNA expression levels of adipogenic genes (Cebpα, Pparγ, and Fabp4) and lipogenic genes (Srebp1c, Fas, and Scd1). These results suggest that SE50 is superior to other ethanol extracts in phenolic contents, antioxidant and anti-obesity activities, and it could be used as a nutraceutical for anti-obesity.
