RESUMO:

The moringa oleifera Lam is a tree of Indian origin with several utilities in the areas of pharmaceutics, fuels, water purification and mainly food. The plant has a better development in dry climates. The culture of use as food is very broad in some African countries and with widespread expansion in Latin and Asian countries because of its rich nutritional value. In this work were realized the determination of macro and micronutrients of the internal and external part of the bark, and seeds of two types of moringas, existents in the UFRN and EAJ to determine the contents of moisture, ash, proteins, fats, carbohydrates and fiber. Make a comparison between these and, if possible, compare with other analyzes made with the plant from other locations. The two samples were divided into three parts each: internal and external part of the shell, and seeds, where they were sprayed and kept in plastic containers. After preparation of the samples, moisture and ash determinations were performed, lipid extraction by Soxhlet, Proteins, by the Kjeldahl method. Fibers, with the equipment to determine fibers. Some metals by ICP-OES, in addition to making FTIR-ATR and TG/DSC. The results showed an optimum lipid content in the seeds (29.26 and 35.83%), whereas in the pulp and in the peels, the contents were well below, in comparison to the seeds (ranging from 0.4 - 1.2 %). Protein contents had a high seed content (30.46 and 34.57%), while pulp and peel had a much lower content (ranging from 3.5 - 6.5%). The fiber contents of the seeds (22.43 - 35.81%), pulp (14.41 - 26.85%) and bark (15.61 - 27.82%). The metals found in the seeds of the two samples were Ca, Cu, Fe, Mg, Mn, K, Na and Zn. The results found will be important for comparisons with future research, of trees of the same species from other localities and different environments, and also to make a nutritional table of the bark and seeds of moringa for future uses.
