Some Amazonian plants, beneficial to health, from Kichwa communities far from the colonized sector are described and laboratory results on antioxidants are presented. The methodology used was based on documentary searches and laboratory results as part of the functional food project, UEA. In the region, 107 species are reported in associated and rotating cultivation systems called chacras and up to 886 food, medicinal, ritual, flavoring, cosmetic and toxic uses of flora species known in the tropical rainforest, western Amazon, considered one of the most biodiverse areas of the planet; home of indigenous peoples with ancestral knowledge about medicinal and food plants, which deserve further laboratory verification. This work presents results of analysis of polyphenolic and antioxidant activity of Maytenus macrocarpa (chuchuhuaso), Theobroma cacao (cacao), Ilex guayusa (Guayusa), Musa acuminata AA ("orito" plantain), as well as the evaluation of phenolic compound contents in powders of Psidium guajava (guava), Tagetes filifolia Lag (wild anise), Allium ursinum (wild garlic), seeds of Plukenetia volubilis (sacha inchi) and tubers of Colocasia esculenta (Chinese potato) and their effect as phytobiotic additive, universities in the Amazonian territory should increase the exploration of sources of secondary metabolites for the pharmaceutical, cosmetic and functional food sectors, in order to promote strategies to improve social and economic conditions, such as ventures based on local resources and strengthening food security.
