Food and Nutrition Sciences (FNS) , 2016, DOI: 10.4236/fns.2016.712111
Abstract: Cubiu fruits (Solanum sessiliflorum Dunal, Solanaceae) are known for their high nutritional value and low caloric content. This work aimed at evaluating biochemical indices of cubiu fruits according to different tissues (peel, pulp and placenta) and ripening stages (green, turning, ripe and fully ripe). The fruits were randomly harvested to investigate sensory aspects (colorimetry, blanching effect, pigments) and biochemical indices (moisture and dry matter, Total Soluble Solids (TSS), pH, Titratable Acidity (TA), TSS/TA ratio, ascorbic acid, Alcohol-Insoluble Solids (AIS), pectinesterase activity and pectin content). The analyses were performed at the laboratory of Instituto Nacional de Pesquisas da Amazonia (INPA), Manaus, Brazil. The blanching process preserved pulp colors at all ripening stages. Chlorophylls were higher in green peels; flavonoids and carotenoids, in fully ripe peels. Anthocyanins were entirely absent. Pulp (turning fruits) showed the highest moisture content (91.05), followed by ripe pulp (90.70) and fully ripe pulp (90.62). Pulp TSS changed little whereas placenta TSS declined and were associated with increased TA and pH reduction (fully ripe fruits). Pulp pH and TA varied little whereas placenta pH was notably low and TA was remarkably high (fully ripe fruits). Pulp TSS/TA ratio showed predominance of TSS while in placenta, there was predominance of organic acids. AIS, precursors of pectin, were stable during ripening. The statistical analysis of dietary fiber content showed one modal value in the AIS. In pulp, pectinesterase activity correlated inversely with pectin content. Cubiu fruits were significant sources of bioactive compounds, e.g. chlorophylls, flavonoids and carotenoids, predominantly in the peel and the pulp; soluble functional fibers, e.g. pectin (g/100 g fresh weight), particularly in the green peel (1.00) and the fully ripe pulp (1.12), and other versatile molecules, e.g. ascorbic acid (mg/100 g fresh weight), especially in the fully ripe peel (32.45) and placenta (24.84) and the turning placenta (21.27). Cubiu fruits are rich in ascorbic acid and should be included in the human diet.

International Journal of Agronomy , 2012, DOI: 10.1155/2012/524075
Abstract: This study aims to evaluate the effect of harvest date on the chemical composition of patauá (Oenocarpus bataua Mart.). Fruits were harvested monthly during the harvest season (June–December, 2009) from native plants in the Adolpho Ducke Forest Reserve located in Manaus, Amazonas, Brazil. The patauá was assessed for pulp yield and chemical composition. Variations in the bunch size, quantity of fruits, chemical constituents and calories occur throughout the season. The pulp yield showed two plateaus, the first from June to September and the second from October to December. The pulp yield was highest in the last three months, the amount of added water equilibrates the total solids and the lipids stood out as the major chemical constituent. At the end of harvest, the patauá became dry and oily and less fibrous. Despite the significant differences, considering that the pulp yield and solids content can be standardized by added water, the entire period of the season may be indicated for the patauá can be periodically collected and considered as a high-energy food for the people of Amazon. 1. Introduction The Amazon has a great diversity of fruit species, and many of them are domesticated and present importance in the primary sector and commerce [1, 2]. Various palms native to Amazonia and other tropical regions of Latin America have been the subject of research and development and require sustainable extractivism [3]. This activity allows the exploitation of products from the forest and of biodiversity valorization [4, 5]. In the Amazon, the fruits of the palm trees such as a?aí (Euterpe oleracea and E. precatoria), bacaba (Oenocarpus bacaba), buriti (Mauritia flexuosa), inajá (Maximiliana maripa), and patauá (Oenocarpus bataua) have similarities in the process of production, consumption, and consistency of pulps [2]. Before the pulping, all fruits should remain immersed in water slightly tepid to softening of the edible portion. Then, in pulping process is necessary the addition of the water. In the pulper occurs the scraping/pressing of the fruit (the edible portion is released and fragmented) followed by sieving (retention of the seeds and fragments non-crushed) and finally getting the pulp completely homogenized. This highly dense juice is popularly known as pulp or “wine” and consumed, added or not, of the manioc flour, “tapioca” flour, salt, or sugar [4, 5]. The other similarity between them is due to high content of unsaturated fatty acid in buriti, tucum? (Astrocaryum vulgare), inajá, mari (Poraqueiba paraensis), and patauá [6]. The color,

Abstract: dapsone (dds) (4,4'diaminodiphenylsulfone), the drug of choice for the treatment of leprosy, frequently induces hemolytic anemia and methemoglobinemia. n-hydroxylation, one of the major pathways of biotransformation, has been constantly related to the methemoglobinemia after the use of the drug. in order to prevent the dapsone-induced hemotoxicity, n-acetylcysteine, a drug precursor of glutathione, was administered in combination with dds to male wistar rats, weighting 220-240 g. the animals were then anaesthetized and blood was collected from the aorta for determination of plasma dds concentration by hplc, determination of methemoglobinemia and glutathione by spectrophotometry, and for biochemical and hematological parameters. our results showed that n-acetylcysteine enhanced dapsone-induced methemoglobinemia due to increased dapsone plasmatic concentration and consequent increased n-hydroxylamine formation. we concluded that drug interactions with dapsone require individually studies in order to avoid undesirable effects of dapsone.
