Walp) ? uma das principais culturas alimentares do nordeste brasileiro. No Rio Grande do Norte, o feij?o caupi, feij?o vigna ou feij?o macassar, como ? conhecido, tem grande import?ncia socioecon?mica como fonte de nutrientes na alimenta??o humana, com grande destaque entre os produtos agr?colas. Para melhorar a produtividade e resist?ncia contra pragas, duas cultivares foram desenvolvidas, exclusivamente pela EMPARN (Empresa de Pesquisa Agropecu?ria do Rio Grande do Norte), por melhoramento gen?tico. As amostras foram fornecidas pela EMPARN, sendo duas melhoradas (Potiguar e Riso do ano) e duas crioulas (Costela de vaca e Canapu). As sementes foram trituradas e transformadas em farinhas e com as amostras foram realizadas as determina??es de umidade e cinzas por m?todos gravim?ticos, lip?deos por extra??o com Soxhlet, fibras com determinador de fibras, carboidratos por diferen?a e minerais por ICP-OES, exceto o f?sforo analisado por UVvis. Os resultados mostraram um alto conte?do de fibras (55,55% e 55,32% amostras melhoradas e 50,04% e 50,32% amostras crioulas) e prote?nas (25,52% e 25,27% amostras melhoradas e 27,23% e 24,99% amostras crioulas). Comparando os resultados dos teores de minerais, as cultivares melhoradas se destacaram em rela??o a Ca, Co, P, Mg, Mo e Na. As cultivares crioulas apresentaram melhores resultados de Cu, Cr (baixo teor), Fe, Mn, Ni, K e Zn. Os resultados obtidos ser?o importantes em futuras pesquisas nutricionais e para constru??o de uma tabela brasileira de composi??o qu?mica de alimentos. / The cowpea (Vigna unguiculata L. Walp) is a major food crops in northeastern Brazil. In Rio Grande do Norte, the cowpea, vigna beans or cowpea, as it is known, has great socioeconomic importance as a source of nutrients in food, with great emphasis among agricultural products. To improve productivity and resistance to pests, two cultivars were developed exclusively by EMPARN (Agricultural Research Corporation of Rio Grande do Norte), for breeding. The samples were provided by EMPARN, two improved (Potiguar and Laugh year) and two landraces (Rib of beef and Canapu). The seeds were ground and made into flour samples and the determination of moisture and ash by gravim?ticos methods, lipids by Soxhlet extraction, fibers with determiner fiber, carbohydrates by difference and minerals by ICP-OES were performed except the match analyzed by UVvis. The results showed a high fiber content (55.55% and 55.32% and 50.04% improved samples and 50.32% creole samples) and protein (25.52% and 25.27% improved and 27 samples, 23% and 24.99% creole samples). Comparing the results of the mineral content, the improved cultivars stood out in relation to Ca, Co, P, Mg, Mo and Na. Creole cultivars showed better results for Cu, Cr (low), Fe, Mn, Ni, K and Zn. The results will be important in future nutritional research and to build a table of Brazilian chemical composition of foods.
