“…Fruit weight was the characteristic that presented the highest CV, corroborating with the results found in this study. In contrast, the mean and maximum values for fruit weight, diameter and width were lower than those reported by Oliveira et al (2011) and Alves et al (2013), evidencing that the collection under study has a variability for these traits and can thus establish a selective process according to the interest in standardization and generation of a new cultivar.…”

Gabirobeira is a fruit tree native to the Brazilian Cerrado with a good productivity and acceptance by the local population and with good prospects for processing. Even with the growing interest in the industry and its potential use, information on gabirobas is limited. Therefore, the knowledge of the development, the characteristics of fruits and the genetic divergence is fundamental to define actions of domestication and adaptation to the productive system. The objective of this study is to determine the genetic variability of 173 genotypes of Gabirobeira from the Jataí-Goiás germplasm collection based on plant and fruit morphological traits. The evaluations were carried out in two periods, and eleven morphological traits were evaluated. Based on data, we performed statistical descriptive analysis, correlation analysis, estimation of relative importance of traits and cluster analysis using multivariate techniques (Tocher and UPGMA). The results showed variability and, among the genotypes studied, it was verified that the lowest and the highest CV (15.8% and 102.49%) were observed for fruit width and number of branches. The mean values obtained for soluble solids ranged from 6 to 26 ºBrix. The contribution of different traits assessed for variability ranged from 0.10 to 27.55%. The dissimilarity varied from 3.64 to 80.35, with an average of 23.083. Both grouping methods formed 18 groups. These results show that the germplasm collection presents variability, which can be used as a guide for its maintenance with the possibility of exploring this variability in future genetic improvement works.Additional keywords: Campomanesia; germplasm; multivariate techniques.

Com base nos dados, realizaram-se a análise estatística descritiva, correlação, estimação da importância relativa dos caracteres e análise de agrupamento, por meio de técnicas multivariadas (Tocher e UPGMA). Os resultados evidenciam existência de variabilidade e, entre os genótipos em estudo, verificou-se que o menor e o maior CV (15,8%, 102,49%) foram observados para a largura do fruto e o número de ramificações. Os valores médios obtidos de sólidos solúveis variaram de 6 a 26 o Brix. A contribuição de diferentes caracteres avaliados para a variabilidade variou de 0,10 a 27,55%. Já a dissimilaridade var...

“…In a study of optimization for extraction of bioactive compounds in gabiroba, pitanga-do-cerrado (Eugenia punicifolia) and pêra-do-cerrado (Eugenia klostzchiana) phenolic compounds indices of 385, 364, and 271 mg GAE per 100 g, respectively, were reported (Rocha et al, 2011). Alves, Alves, Fernandes, Naves, and Naves (2013) performed extraction in methanol, and reported that fruits of gabirobeira had an average value of 1222 mg GAE per 100 g. In addition, Lima, Castro, Sabino, Limas, and Torres (2016) reported indices of 229 and 511 mg GAE per 100 g for yellow gabiroba (Campomanesia lineatifolia) and myrtle (Blepharocalyx salicifolius), respectively. Infante, Rosalen, Lazarini, Franchin, and Alencar (2016), in tests of fruits from the genus Eugenia, reported levels of 151, 183, 266 and 178 mg GAE per 100 g for araçá-pitanga (Eugenia leitonii), cherrygrove, grumixama (Eugenia brasiliensis) and pessegueiro-do-mato, respectively.…”

Belonging to the family Myrtaceae, 'sete capotes' is a plant native to the Atlantic Forest biome. It produces yellow-green fruits between February and May. Although used for consumption by local populations, studies of the fruit are rare. The present work aimed at characterize the fruit in terms of physicochemical properties. We quantified mass, volume, moisture, pulp yield, pH, titratable acidity, soluble solids/titratable acidity, proteins, lipids, total sugars, reducing sugars, ash, macronutrients, micronutrients, pectin, vitamin C and phenolic compounds. Compared with commercial fruits and other native fruit trees, sete capotes is unusual for its pulp yield, vitamin C levels, total phenolic compound content, protein levels, calcium content, potassium levels and iron content. Through the results it is verified of the fruit as a functional food, mainly because of its nutritive content and because of its bioactive compounds. Our data emphasize the importance of study of the constituents of native flora. absorbent paper, packed in polyethylene bags and frozen at -20ºC until analysis. Prior to analysis, the fruits were removed from refrigerator, and juice was extracted by manual pressing through a sieve. We also obtained flour from pulped and oven-dried fruits at 55ºC that were ground in a mill. The variables analyzed are described below, taking into account that humidity, pH, SS/AT ratio, lipids, total sugars, ash and vitamin C were quantified according to the methodology proposed by the Instituto Adolfo Lutz (2008).Volume and mass: For mass determination, we used a semi-analytical balance (Mars AD430). The volume was measured by an indirect method: Fruits were immersed in a known quantity of distilled water, using graduated cylinder to observe the displacement of the liquid. The mean value of mass and volume of the samples were expressed as grams and cm 3 .Humidity: Was used to determine the percent moisture content, and the percentage humidity was calculated by the loss of water by desiccation of fruits after 48 hours in an oven at 55ºC.Pulp yield and number of seeds per fruit: The calculation of pulp yield was performed according to the methodology of Santos, Lima, Petkowicz, and Candido (2013), comparing fruit weight before and after seed removal. The mean value of yield was expressed as a percentage, as was the mean number of seeds in fruits.PH: The pH of the juice diluted 1:10 in distilled water was measured with the aid of a calibrated pH meter (MSTecnopon-MPA210).Titratable acid -TA: Consisting of titrating juice diluted 1:10 with a standard solution of 0.1 N NaOH to pH 8.2. The results were expressed as grams of citric acid per 100 mL.Determination of soluble solids by refractometry -SS: The analysis of soluble solids by refractometry was performed on an Abbé-type bench refractometer (BEL-RTM). Readings were performed on fruits at the same maturation stage, and the results were expressed in Brix degrees.SS/TA ratio: Based on the calculation of the SS/TA ratio (Brix degrees divided by the value of Titrata...

“…Portanto, entre os extratos estudados, o extrato hidro alcoólico foi mais eficiente na extração dos fenólicos tanto na casca quanto na polpa, e o extrato aquoso foi mais eficiente na extração dos fenólicos na semente. Resultado superior ao encontrado para polpa de gabiroba, foi Mendes et al, v.11, n.39, p. 68-72, Dourados, 2018 relatado por Alves et al (2013), sendo 1.222,59 mg AGE.100g-1 . Segundo, Martins et al (2011) a concentração de compostos fenólicos de um alimento pode variar conforme as condições geográficas e ambientais da região de origem e os fatores fisiológicos e genéticos da planta.…”

O bioma Cerrado apresenta uma rica variedade de espécies frutíferas detentoras de características sensoriais e nutricionais ainda pouco exploradas cientificamente e comercialmente. Este trabalho tem como objetivo determinar os compostos bioativos de frutos de gabiroba, oriundos do município de Guarda-Mor, MG. 70 frutos maduros e in natura, foram selecionados aleatoriamente para a realização da análise biométrica, da qual apresentou os seguintes resultados expressos em média: diâmetro longitudinal 17,57mm, diâmetro transversal 17,39mm, casca 1,78 g, polpa 0,40 g e semente 2,11 g. Após, o despolpamento dos frutos, casca, polpa e semente foram analisadas com a determinação de pH, acidez, sólidos solúveis, umidade, cinzas, vitamina C, β-carotenos e fenólicos totais. O conteúdo de vitamina C encontrado na casca foi de 120,47 mg/100 g, sendo maior que ao encontrado na polpa que foi de 89,52 mg/100 g. Na determinação dos β-carotenos e fenólicos totais, as análises foram realizadas nos meios aquoso, hidro alcoólico e etílico. Para os β-carotenos, dentre os três meios analisados, a extração em meio aquoso foi a que apresentou uma melhor eficiência na casca 0,29 μg/100 g, polpa 0,92 μg/100 ge semente 0,48 μg/100 g. Já para os fenólicos totais, o extrato hidro alcoólico apresentou maior eficiência na casca 1,22 mg/100 g e polpa 1,32 mg/100 g, e o extrato aquoso apresentou maior eficiência na semente 1,31 mg/100 g. A gabiroba apresentou resultados expressivos para os compostos bioativos. Seu potencial de exploração comercial é grande.
