Abstract: This study examines the antioxidant activity and total phenolic content of commonly consumed cereals and legumes, including wheat (Triticum aestivum), chickpea (Cicer arietinum), and bean (Phaseolus vulgaris). The samples were extracted using 80% methanol. Antioxidant activity was evaluated by the DPPH free radical scavenging method, while total phenolic content (TPC) was determined using the Folin–Ciocalteu assay.

The results indicated that legumes generally showed higher phenolic content and stronger antioxidant activity compared to cereals. Among the samples, chickpea extract had the highest total phenolic content (2.45 ± 0.08 mg GAE/g), whereas wheat had the lowest value (1.12 ± 0.04 mg GAE/g). A strong positive correlation (r = 0.91) was found between total phenolic content and antioxidant activity, suggesting that phenolic compounds play a major role in antioxidant capacity.

Overall, these findings highlight the nutritional value and functional potential of cereals and legumes as natural sources of antioxidants for human diets.
