“…Esses resultados são similares aos de outras frutas tropicais, como cupuaçu, caju e murici, nas quais os ésteres são os principais constituintes voláteis da polpa (FRANCO;JANZANTTI, 2005;REZENDE;FRAGA, 2003). Os principais constituintes identificados foram o hexanoato de etila (valor médio= 55,92 ± 25,10%), (E)-β-ocimeno (17,65 ± 11,88%) e octanoato de etila (4,79 ± 5,07%).…”

RESUMO -O fruto do pequizeiro (Caryocar brasiliense Camb.) apresenta considerável variabilidade em suas características físicas e químicas, segundo a região de origem, e pesquisas com frutos procedentes do Estado de Mato Grosso são escassas na literatura. Neste estudo, foram analisadas as características físicas, a composição químico-nutricional e os constituintes voláteis da polpa de pequi coletado em diferentes locais do Estado de Mato Grosso. Os frutos foram analisados quanto à cor (L*, a*, b*, h° e C*), à massa e ao rendimento do mesocarpo externo, pirênios e polpa. Foram determinados a composição centesimal, os teores de carotenoides totais, o perfil de ácidos graxos e de constituintes voláteis da polpa, e analisada a composição físico-química do solo dos locais de coleta.. Constatou-se que o fruto é composto por 80-85% de mesocarpo externo, 11-15% de pirênios e 4-7% de polpa, que é rica em lipídios (46-51g 100g -1 ), carotenoides totais (15-27mg 100g -1 ) -que foram associados à tonalidade e à intensidade da cor (h° e C*) da polpa -e fibra alimentar (8-15g 100g -1 ). Os principais constituintes voláteis da polpa de pequi foram o hexanoato de etila, (E)-β-ocimeno e octanoato de etila. O isobutirato de alila, 3-hexanol, 4-metil-2-pentanol, mirceno, (Z)-di-hidroapofarnesol, β-eudesmol e (E-E) geranilalinalool foram descritos pela primeira vez nos óleos essenciais da polpa de C. brasiliense. Grande parte da variância total dos voláteis foi explicada pelo conjunto de variáveis do solo, destacando-se o silte, o P e o Mg 2+ . Termos para indexação: Pequi, composição centesimal, carotenoides, ácidos graxos, substâncias voláteis. PHYSICAL CHARACTERISTICS, CHEMICAL-NUTRITIONAL COMPOSITION AND ESSENTIAL OILS OF Caryocar brasiliense NATIVE FROM THE STATE OF MATO GROSSOABSTRACT -The fruit of pequi tree (Caryocar brasiliense Camb.) presents a considerable variability in both physical and chemical characteristics, according to the sampling region, and research with fruits collected in the state of Mato Grosso are scarce in the literature. In this study, it was analyzed the physical characteristics, the chemical-nutritional composition, and the volatile compounds of pequi pulp, collected from different places of the state of Mato Grosso. The fruits were analyzed according to color (L*, a*, b*, h° and C*), mass and external mesocarp, seed (pyrenes) and pulp yield. The proximate composition, total carotenoid content, fatty acids profile and volatile compounds of the pulp were determined, and the physicochemical composition of the soil was also analyzed. It was found that the fruit is composed by 80-85% of external mesocarp, 11-15% of pyrenes and 4-7% of pulp, that is rich in lipids (46-51g 100g -1 ), total carotenoids (15-27mg 100g -1 ) -which were related to the color tonality and intensity (h° and C*) of the pulp -and dietary fiber (8-15g 100g -1 ). The main volatile compounds of pequi pulp were ethyl hexanoate, (E)-β-ocimene and ethyl octanoate. The allyl isobutyrate, 3-hexanol, 4-methyl-2-pentanol, myrcene, (Z)-dihydroa...

“…The murici, fruit of B. verbascifolia, can be consumed in natura by the population. When ripe, it presents a yellow color with a strong odor similar to that of stale cheese [5,6]. The pulp is fleshy and soft, and can also be consumed in the form of juices, jellies, ice creams and liquors [6].…”

-Introduction. The Cerrado is the largest biome in the state of Minas Gerais, Brazil; it presents an enormous biodiversity represented by fruit species, highlighting murici (Byrsonima verbascifolia). The objective of our study was to investigate the physical and physicochemical characteristics, occurrence and concentration of carotenoids, vitamin C, vitamin E and folates in murici fruits from the Cerrado of Minas Gerais, Brazil. Materials and methods. Titratable acidity was determined by volumetric neutralization, pH by potentiometry, soluble solids by refractometry, moisture using an oven, ash using a muffle furnace, protein by the micro-Kjeldahl method, total dietary fiber by the nonenzymatic gravimetric method and lipids by Soxhlet extraction; carotenoids and vitamin C were analyzed by HPLC-DAD, and vitamin E and folates by HPLC with fluorescence detection. Results and discussion. The murici pulp contained 7.47 g·100 g -1 carbohydrates, 5.13 g·100 g -1 lipids, 13.58 g·100 g -1 fibers and 71.58 g·100 g -1 moisture. The pH, titratable acidity and soluble solids were 3.93, 0.77 g citric acid·100 g -1 and 10.73°Brix, respectively. The results indicated that the fruit is an excellent source of fiber and vitamin C (27.24 mg·100 g -1 ), a good source of vitamin E (1819.72 µg·100 g -1 ) for children and a source for adults and pregnant women. Folates were not found in murici. Conclusion. Murici stands out with regard to its nutritional value and can contribute significantly to the supply of nutrients, especially fiber and vitamin C. Thus, consumption of these fruits should be encouraged among families residing in the Cerrado and in other regions of Brazil. Brazil /

“…), a tropical tree of the family Malpighiaceae, and like all plants of this genus, and most of the neotropical species of this family, have flowers that instead of nectar, have an abundant lipid composition (oil) (Rezende and Fraga, 2003;Ribeiro et al, 2008). The genus Byrsonima, whose species are known popularly as murici, is distributed in the savanna and the Neotropics (Benezar and Pessoni, 2006).…”

“…It has some morphological characteristics typical of cerrado plants, usually medium-sized trees reaching 5 m. Its fruit, when ripe, is yellow, with 1.5 to 2 cm diameter, it has a strong odor, an exotic taste and is rich in vitamins and minerals such as calcium, phosphorus and iron. It is very popular in the North and Northeastern parts of Brazil, and its pulp is commonly used to make juices, wines, liquors and sweets (Rezende and Fraga, 2003;Giraldo-Zuniga et al, 2006;Rego et al, 2006). B. coccolobifolia often occur in areas of open vegetation in South America, with records of its occurrence in Brazil, Bolivia, Venezuela and the Guianas.…”

Byrsonima coccolobifolia is a tropical plant from the Malpighiaceae family, distributed in the neotropical savanna fields and pollinated by bees known as "collecting-oil bees". In this study, conducted in a Cerrado area located on a farm in the city of Silvânia, GO, the following hypothesis was tested: the greater the isolation degree of a plant, the lower its fruit production due to access difficulties for pollinators. Using a linear regression analysis, it was possible to relate the fruiting rate with the degree of isolation of each B. coccolobifolia individual and consequently it was found that the isolation had no influence on the pollination rate, an unexpected event that can be explained by the distance amongst individuals not being large enough to limit the movement of pollinators, or because cross-pollination was not the predominant form of reproduction, since the rate of cross-pollination was similar to self-pollination. It was also found that the proportion of fruits produced was lower than expected, a factor which may also have influenced the results.Keywords: pollination, isolation, habitat alteration, fruit production. Polinização de Byrsonima cocolobifolia: isolamento de curta distância e as possíveis causas para baixa produção de frutos ResumoByrsonima coccolobifolia é uma planta tropical da família Malpighiaceae, distribuída no Cerrado e polinizada por abelhas conhecidas como "abelhas coletoras-de-óleo". No presente estudo, realizado em área de cerrado localizada em uma fazenda no município de Silvânia, GO, foi testada a hipótese de que quanto maior o grau de isolamento de uma planta, menor sua produção de frutos, devido à dificuldade de acesso dos polinizadores. Através de uma análise de regressão linear foi possível relacionar a taxa de frutificação ao grau de isolamento de cada indivíduo de B. coccolobifolia, e verificou-se que o isolamento não exerceu influência alguma na produção de frutos, fato inesperado que pode ser explicado pela distância entre os indivíduos não ser suficientemente grande a ponto de limitar o trânsito de polinizadores, ou pelo fato da polinização cruzada não ser a forma predominante de reprodução, uma vez que a taxa de polinização cruzada foi semelhante à de autopolinização. Verificou-se ainda que a proporção de frutos produzidos foi abaixo do esperado, fator que também pode ter influenciado os resultados.Palavras-chave: polinização, isolamento, alteração de habitat, produção de frutos.
