Plants used by the rural community of Bananal, Mato Grosso, Brazil: Aspects of popular knowledge.

Studies in rural communities are important to maintain popular knowledge between generations, as well as to identify new species for pharmaceutical production. Thus, the objectives of this study were to determine which plant species the rural community of Bananal, Mato Grosso, Brazil, uses by calculating the levels of fidelity and concordance regarding species uses among residents and to determine if there is a relationship between the number of known useful plants and levels of education, age, and residence time. Ethnobotanical data was collected from residents of the community through semi-structured interviews in January/December/2016. Species diversity was calculated using Shannon-Wiener, Level of Fidelity (LF), Correction Factor, and the Percentage of Agreement regarding the Main Uses (AMU). Statistical tests were performed using generalized linear models (GLM) in the R environment. The plant use indications were grouped according to the International Classification of Diseases and Related Health Problems (ICD 10). We found 152 species belonging to 130 genera and 67 families. The most frequently used plant parts were leaves, and decoction was the most frequent preparation mode. Strychnos pseudoquina was the species with the highest amount of use indications. The diversity index was 4.5 nats/ind-1. The body system with the most citations was the code XVIII of ICD 10, corresponding to the species: alfavaca, mentraste, terramicina, angelim, fedegoso. Medicinal species with AMU values higher than 25% were: Strychnos pseudoquina, Plectranthus barbatus, Citrus sinensis cv. pera, Cymbopogon citratus. There was a relationship between the number of useful plants and the residence time of the participants. The Bananal community revealed high species richness and the relationship of knowledge showed that the older the residents and the longer their residence time in the community, the more knowledge they acquired.

Ethnobotany and regional knowledge: combining popular knowledge with the biotechnological potential of plants in the Aldeia Velha community, Chapada dos Guimarães, Mato Grosso, Brazil / Etnobotánica y conocimiento regional: Combinando conocimiento popular con el potencial biotecnológico de plantas en la comunidad de Aldeia Velha, Chapada dos Guimarães, Mato Grosso, Brasil

Ethnobotanical studies were conducted in the Aldeia Velha community (Mato Grosso, Brazil) through semi-structured interviews. The majority of participants were women who have resided for more than 20 years in the community. Seventy-two species (39 families) were cataloged; leaf tea was the most common form of preparation. Over 80% were medicinal, with much of it is used for inflammation and disorders of the respiratory, digestive or genitourinary systems. Finally, seven species occurring in the Chapada dos Guimarães cerrado have biotechnological potential, especially Amburana cearensis, Mikania glomerata and Pseudobrickellia brasiliensis, where conservation measures are necessary due to their high risk of extinction and/or vulnerability.

El presente trabajo muestra resultados de un estudio etnobotánico realizado en la comunidad Aldeia Velha (Mato Grosso, Brasil). La información de uso de las especies fue colectada a través de entrevistas semiestructuradas, aplicadas a mujeres que residen hace más de 20 años en ese local. Adicionalmente fueron catalogadas 72 especies distribuidas en 39 familias. Entre las especies catalogadas más del 80% fueron informadas como medicinales, generalmente utilizadas para el tratamiento de inflamaciones, trastornos del sistema respiratorio, digestivo y genitourinario. Entre las formas de preparacióno la infusión de hojas fue la forma de consumo más común. En este trabajo fueron identificadas especies presentes en el Cerrado Chapadense que muestran un importante potencial biotecnológico destacándose Amburana cearensis, Mikania glomerata y Pseudobrickellia brasiliensis; debido a su alto riesgo de extinción y/o vulnerabilidad por ello son necesarias medidas conservacionistas de esa biodiversidad.

Quintais urbanos de Mirassol D'Oeste-MT, Brasil: uma abordagem etnobotânica / Urban homegardens of Mirassol D'Oeste-MT, Brazil: an ethnobotany stady

Quintais são espaços de fácil acesso e cômodos para os moradores cultivarem uma diversidade de espécies que desempenham funções de estética, lazer, alimentação e medicinal, dentre outras. O objetivo deste trabalho foi o de descrever a composição florística e a respectiva utilização em quintais urbanos de Mirassol D'Oeste, MT, (15º 45'30"S e 058º16'36"W), com a coleta de dados envolvendo: entrevistas estruturadas e semi-estruturadas aplicadas a 29 moradores; coleta simultânea do material botânico das espécies indicadas, incorporação destas no Laboratório de Botânica da UNEMAT, Cáceres e análise da freqüência absoluta e relativa das espécies mais citadas e encontradas nos quintais. Foram registradas 397 denominações locais de plantas (etnoespécies), 275 taxa reunidos em 79 famílias destacando-se com maior número de espécies: Solanaceae (23), Asteraceae (17), Lamiaceae (14), Rosaceae (12) e Verbenaceae (9). Os atributos alimentar e ornamental representam, individualmente, 35% das espécies e o medicinal, 29%. Algumas plantas detêm até quatro potencialidades. Do universo vegetal conhecido e utilizado localmente as espécies nativas correspondem a 8%, resultado considerado baixo comparando-se aos obtidos em populações mato-grossenses radicadas no Cerrado e Pantanal. Essa população manifesta por meio de suas práticas uma tradição agrícola em interface às características de uma sociedade urbano - industrial coabitando em espaços comuns, o quintal.

A home garden is a small track of ground next to or surrounding a house where its residents can cultivate a diversity of plants, whose function is aesthetic, leisure, food, medicinal among others. The aim of this work was to study the floristic composition of urban homegardens in the city of Mirassol D'Oeste, state of Mato Grosso, coordinate 15º45'30"S and 58º16'36"W. For colleting data we interviewed 29 residents using structured and semi-structured interviews; and, simultaneously collected botanical species which we analysed at the Mato Grosso State University Botanical Laboratory, in Cáceres. We made statistical analyses using absolute frequency and relative frequency to quantify and specify the botanical species found in the gardens. We registered a total of 397 ethnobotanical species and grouped 275 taxa in 79 botanical families. The highest numbers among them were 23 species of Solanaceae, 17 Asteraceae, 14 Lamiaceae , 12 Rosaceae and 9 species of Verbenaceae. Food and ornamental attributes represented 35 % of the species and medicinal 29% . Some species had up to four potentialities. From the known plant universe used locally, native species corresponded to 8%. This percentage was considered low when compared to that of the population living in the Pantanal and cerrado areas. This population demonstrated an interface between agricultural tradition and the characteristics of urban-industrial society living in common spaces: the homegardens.
