Unconventional Food Plants considered as "bush", weeds, exotic fruits that are no longer consumed by the population, among other definitions, are part of the plant diversity in our country. They can grow on crops of conventional cultivation; however, despite the ecological value, most of these plants can also be classified as food plants. They can appear in the form of tubers, roots, rhizomes, leaves, stems, corms, flowers, fruits, and seeds. In the state of Pernambuco, there are agroecological fairs that sell organic products and some of these plants. The study aimed to conduct cataloging of Non-Conventional Food Plants (PANC) that are marketed in agroecological fairs located in large urban centers. Visits were made to four main agroecological fairs, and the collected plants were subjected to classification and analysis of their chemical composition. The composition of these plants had valuable nutritional content. Therefore, it was found a variety of PANC being commercialized in agroecological fairs that were classified and analyzed in their nutritional content, which helps in the diffusion of new products to the consumer's table, in addition to recognizing the work of family farmers who work with this type of plant.
