Conteúdo: | ABSTRACT - Isoflavones and rutin are important bioactive compounds found in soybean plants. These compounds are widely known to have beneficial effects on human health and to contribute on soybean plant defense against herbivores.To support studies related to conventional or genetic improvement of soybean plants through the selection ofplants with high levels of bioactive compounds, two highly sensitive and promising methodologies based on voltammetry have been optimized and validated to determine isoflavones and rutin levels in 24 Brazilian soybean cultivars and in its different organs (leaf, seed and root). After statistical analysis, the contrasts of total isoflavones concentration in soybean seeds indicated the formation of three groups: one group represented by the cultivar BRS 133 with 902.6μgg-¹ and two groups with mean concentrations ranging from 313.7 to 529.0μgg-¹ and 127.5–233.5μgg-¹, respectively. In soybean roots, the contrasts of total isoflavones concentration indicated theformation of two groups ranging from 679.1 to 1470.6μgg-¹ and 137.1–447.9μgg-¹, respectively. For soybean leaves, only three cultivars presented rutin and the highest concentration was found to be 1438.8μgg-¹. After applying the Scott-Knott test (p<0.05), there was statistical evidence that BRS 133 variety differs from other varieties in terms of isoflavones concentration in seeds. Such evidence pointed out BRS 133 as a promising cultivar to ongoing projects aiming genetic manipulation of soybean plants for uses in soy food products.
