Composition, content of bioactive compounds, and antioxidant activity of fruit pulps from the Brazilian Amazon biome
Provedor de dados: Pesquisa Agropecuária Brasileira
Autores: Virgolin,Lara Borghi; Seixas,Fernanda Rosan Fortunato; Janzantti,Natália Soares.
Abstract: The objective of this work was to evaluate the physicochemical composition, the bioactive compounds, and the total antioxidant activity of the fruit pulps of abiu (Pouteria caimito), achachairu (Garcinia humilis), araza (Eugenia stipitata), bilimbi (Averrhoa bilimbi), and yellow mangosteen (Garcinia xanthochymus) from the Brazilian Amazon biome. Total soluble solid content, total and reducing sugar contents, titratable acidity contents, pH, ascorbic acid content, moisture, protein, lipid, ash, and caloric value were determined. The contents of total anthocyanins, yellow flavonoids, and total carotenoids, besides total phenolic compounds and antioxidant activity, were also evaluated. The abiu pulp showed the highest contents of ash, total sugars,...

ABSTRACT Piper bellidifolium, Piper durilignum, Piper acutilimbum and Piper consanguineum are bushes that occur in the Amazon and are morphologically similar. With the aim of analyzing the chemical profile of the volatile constituents of these species, essential oils from the leaves were obtained through steam distillation and analyzed using gas chromatography-flame ionization detection (GC-FID) and gas chromatograph coupled to a mass spectrometer (GC-MS). The chemical analysis enabled the identification of 95 compounds representing 96.3 ± 0.6% of the P. bellidifolium oil, 95.5 ± 0.71% of the P. durilignum oil, 98.0 ± 1.0% of the P. acutilimbum oil and 96.1 ± 2.1% of the P. consanguineum oil. Although sesquiterpenes were the predominant chemical class in...

Analysis of soybean cropland expansion in the southern Brazilian Amazon and its relation to economic drivers
Provedor de dados: Acta Amazonica
Autores: GUSSO,Anibal; DUCATI,Jorge Ricardo; BORTOLOTTO,Virindiana Colet.
ABSTRACT The agricultural dynamics of soybean expansion have long been recognized as a major driver of excessive land cover change on the southwestern border of the Brazilian Amazon. The hypothesis that the soybean market exerts an influence on land use was investigated by the association between economic indicators and soybean crop dynamics in the state of Mato Grosso (western Brazil). We integrated a historical series of satellite data of soybean cropland expansion and the two main economic variables (selling prices and production costs) for soybean in Mato Grosso. We focused on the relation between profit (the difference between the average soybean price and production costs) and land-use transition to soybean from 2001 to 2013. The spatially explicit...
