Antioxidant Capacity of Cotyledons and Germs of Soybeanb in Relation to Their Isoflavone Content
The aim was to study the relationship between the antioxidant capacity and the isoflavone content of soybean extracts depending on both geographic origin and cultivar. Soybean samples were obtained from two soybean seed parts, germ and cotyledon, from two geographical locations (L1, L2) and two cult...

| description | The aim was to study the relationship between the antioxidant capacity and the isoflavone content of soybean extracts depending on both geographic origin and cultivar. Soybean samples were obtained from two soybean seed parts, germ and cotyledon, from two geographical locations (L1, L2) and two cultivars (Queen, Imari), which gave 8 different samples. HPLC determination confirmed higher isoflavone content in germs than in cotyledons, with higher contents in site L2, and in the Queen cultivar. The antioxidant capacity of soybean samples was determined with two methods, the 2,2-diphenyl-1-picrylhydrazyl scavenging assay and the oxygen radical absorbance capacity assay. The results obtained with both assays showed differences in antioxidant capacity between germ and cotyledon extracts, with a higher antioxidant activity of germ extracts. |
