“…A coleta de dados foi realizada por meio de observações visuais e diretas das plantas presentes no bairro (Passos, 2019), no período de julho a outubro de 2020. No primeiro momento foram percorridas todas as ruas que compõem o bairro São Francisco para realizar o levantamento florístico das espécies de PANC presente nas áreas abertas, calçadas e terrenos baldios, cujo perímetro se encontra delimitado em vermelho (Figura 1).…”

“…As espécies identificadas foram classificadas quanto à família, nome científico e popular (priorizando os nomes usuais na região), hábito e origem, seguindo o banco de dados da Flora e Funga do Brasil. Para a classificação quanto às formas e partes de uso foram apresentadas as mencionadas pelos moradores e para aquelas sem registro de uso, são evidenciadas as existentes na literatura que trazem essas informações (Kinupp e Lorenzi, 2014;Passos, 2019).…”

Realizou-se a caracterização das Plantas Alimentícias Não Convencionais (PANC) encontradas no bairro São Francisco, município de Itaiçaba, Estado do Ceará, e para isso, buscou-se realizar o levantamento das PANC e compreender o conhecimento dos moradores sobre a utilização dessas plantas na alimentação. A coleta de dados ocorreu através de observações visuais e diretas das espécies de plantas presentes no bairro, enquanto as identificações foram feitas com auxílio de fotografias, consulta a especialistas, literatura especializada e banco de dados da Flora e Funga do Brasil. Posteriormente, foram aplicados 30 questionários semi-estruturados, acompanhados de turnês-guiadas nos quintais dos moradores. No total, 35 espécies de PANC foram identificadas na localidade. A maioria dos participantes desconhece o termo, o que não significa que não utilizam estas plantas na alimentação, porém o que predomina são as formas e partes convencionais de uso. Neste sentido, o que prevalece é a inexistência de uma diversificação alimentar, já que as plantas com elevado potencial alimentício são negligenciadas.Palavras-chave: alimentação, biodiversidade, Caatinga, etnobotânica, plantas comestíveis.Non-Conventional Food Plants (PANC) and the Challenge of Valuing Unknown Wealth: a case study in the municipality of Itaiçaba, CearáA B S T R A C TThe characterization of Non-Conventional Food Plants (PANC) was carried out in the São Francisco district, municipality of Itaiçaba, State of Ceará, and for that, an attempt was made to carry out a survey of the PANC and to understand the knowledge of the residents about the use of these plants in food. Data collection took place through visual and direct observations of plant species present in the neighborhood, while identifications were made with the help of photographs, consultation with specialists, specialized literature and the Flora e Funga do Brasil database. Afterwards, 30 semi-structured questionnaires were applied, accompanied by guided tours in the residents' backyards. In total, 35 PANC species were identified in the locality. Most participants are unaware of the term, which does not mean that they do not use these plants in food, but what predominates are the conventional ways and parts of use. In this sense, what prevails is the inexistence of food diversification, as plants with high nutritional potential are neglected.Keywords: biodiversity, Caatinga, edible plants, ethnobotany, food.

“…parviflora Cav., popularly known as gallant soldier or picão branco, is an herbaceous native from South America, abundant in agricultural areas of temperate and subtropical regions of the world [8], [9]. This plant is considered a non-conventional food plant and its leaves are used in salads, spices and sauteed in countries of North and South America and South Africa [8], [10], [11], [12], [13]. Dried leaves and the juice of G. parviflora have been used to treat dermatological disorders and hemorrhages, as well as, are used for analgesia and as an antiinflammatory.…”

The study was designed to investigate the chemical composition and the biological effects of G. parviflora and V. polyanthes ethanolic extracts in vitro. Total content of phenols, flavonoids and tannins was quantified by spectrophotometry; chemical characterization was permed by mass spectrometry (ESI (-) FT-ICR MS and APCI (+) FT-ICR MS analysis). Antioxidant activities were determined by FRAP and Fe2+ chelating methods. Extracts cytotoxicity was evaluated in human lymphocytes, sarcoma-180 (S-180) and human gastric adenocarcinoma (AGS) cells, by MTT assay. V. polyanthes presented higher total content of tannins and G. parviflora presented higher amount of phenols and flavonoids. Chemical characterization showed the presence of flavonoids, phenolic acids and sesquiterpene lactones in V. polyanthes extract, and steroids, phenolic acids and fatty acids (Poly Unsaturated Fatty Acids - PUFA) in G. parviflora extract. V. polyanthes extract stood out in the Fe2+ chelation test. G. parviflora extract did not present outstanding antioxidant results in the tested protocols. Both species showed a tendency to promote cytotoxicity in human lymphocyte cells. Regarding the antiproliferative effect, both species were able to reduce S-180 cell viability and G. parviflora extract showed high antiproliferative potential in the assay with AGS cells. These findings reinforce the medicinal use of these plants, as well as suggest their potential use for the development of new drugs and for the treatment of cancers.

“…The population understanding of nonconventional food plants is still abstract and is lost or mixed in the concepts of medicinal plants and spontaneous plants. Therefore, the use of these species for food is still quite limited (BORGES;LIBERATO et al, 2019).…”

This work aimed to evaluate the technical feasibility of lettuce, Indian spinach and taro intercropping under organic fertilizer. The experiment was performed at Água Limpa Farm, belonging to the University of Brasília, located in Brasília - DF, from October 2014 to June 2015. A completely randomized block design with seven treatments and four replications was used. Each experimental plot had 18 m2 (4.5 m x 4.0 m), totaling 28 plots. The following treatments were assessed: lettuce monoculture, Indian spinach monoculture, taro monoculture, lettuce/Indian spinach intercropping, lettuce/taro intercropping, Indian spinach/taro intercropping, and lettuce/Indian spinach/taro intercropping. In all treatments, the following spacings were used: 0.25 x 0.25 m (lettuce), 1.0 x 0.6 m (Indian spinach), and 1.0 x 0.3 m (taro). Crop production was evaluated from sample plants taken from the central part of each plot. Two harvests of lettuce, two of Indian spinach and one of taro were carried out during intercropping. In the first cycle, lettuce highest mean yield values were observed in the lettuce monoculture (3.5 kg m-2) and lettuce/Indian spinach intercropping (3.4 kg m-2). The crop reached the commercial size in both production cycles, except when intercropped with Indian spinach in the second cycle. The highest Indian spinach mean fresh mass was recorded in the lettuce/Indian spinach intercropping (974.7 g plant-1; first harvest) and monoculture (327.5 g plant-1; second harvest). The yield of taro rhizomes was significantly higher when intercropped with lettuce, showing a mean value of 16.8 kg m-2. The intercropping arrangements with lettuce increased yield of nonconventional vegetables. The conventional and nonconventional vegetables’ intercropping technique increased species diversity in the area without interfering in the agronomic performance and quality of the crops.
