Cerrado biome assembles great variety of the Brazilian biodiversity. The agricultural advance is causing the extinction of many species that are not yet studied. Plants from Cerrado are known as source of compounds of high biotechnological interest, which have application on medical and food industries. The study of these compounds are very necessary, to relate the importance of the use flora products for human development and health. In this work, two plant species were studied (Inga alba and Inga cylindrica), on their nutritional contents (lipids, humidity and ashes), quantity of proteins and enzymes (total soluble proteins, peroxidase and protease activity) and their contents of phenolic compounds. Results showed that elemental analysis was very similar for both I. alba and I. cylindrica (lipids 2.49% and 2.62%; humidity 11.93% and 9.37%; ashes 2.98% and 1.25%, respectively). The soluble protein content was very different, showing twenty times more protein in I. alba that in I. cylindrica.  Enzyme content revealed a different profile for both species: two times more peroxidase activity, but four times less protease activity in I. cylindrica than in I. alba. Phenolic compounds were encountered in both plants, in similar concentrations: 111.4 mg g^-1 of flour in I. alba and 114.8 mg g^-1 of flour in I.  cylindrica. These plants revealed a good potential to be explored. The content of protease (643.22 EU g^-1 of flour) in I. alba was comparable to that found in Hymenaea coubaril L. (497 EU g^-1 of flour). Otherwise, the specific activity of peroxidase found in I. cylindrica (89.46 EU mg^-1 protein) and I. alba (40.8 EU mg^-1 protein) was high if compared to the others plants found in the same biome: H. courbaril (15.04 EU mg^-1 protein), Plathymenia reticulata Benth. (0.21 EU mg^-1 protein), Zanthoxylum rhoifolium Lam. (2.84 EU mg^-1 protein) and Salacia crassiflora Mart. (0.24 EU mg^-1 protein).
