“…O interesse por produtos com potencial terapêutico, condimentares e aromáticos vem crescendo a cada dia que passa, tanto no Brasil como no mundo (Martinazzo et al, 2007;Tabaldi et al, 2012). Devido a esta demanda acaba se tornando essencial, além das práticas agrícolas sustentáveis e mais eficientes, o desenvolvimento de técnicas eficientes de secagem e armazenamento para que a biomassa produzida pela planta e suas propriedades químicas possam ser aproveitadas de forma integral e efetiva (Tabaldi et al, 2012).…”

R E S U M OPropôs-se, neste trabalho, avaliar a cinética de secagem de folhas de timbó (Serjania marginata Casar) e ajustar diferentes modelos matemáticos aos valores experimentais de razão de umidade. As folhas de timbó foram colhidas com teor de água inicial de 2,03 ± 0,10 decimal b.s., sendo submetidas à secagem sob condições controladas de temperatura (40, 50, 60 e 70 °C), até o teor de água de 0,08 ± 0,02 decimal b.s. Aos dados experimentais foram ajustados dez modelos matemáticos utilizados para representação da secagem de produtos agrícolas. Com base nos resultados obtidos o modelo matemático de Midilli é o que melhor representa a cinética de secagem para as folhas de timbó. O aumento da temperatura promove: uma taxa maior de remoção de água nas folhas de timbó durante a secagem; aumento do coeficiente de difusão efetivo sendo que esta relação pode ser descrita pela equação de Arrhenius que apresenta uma energia de ativação para a difusão líquida durante a secagem de 81,39 kJ mol -1 para as folhas de timbó; aumento da energia livre de Gibbs, enquanto a entalpia e a entropia decrescem. Drying kinetics of Serjania marginata Casar leaves A B S T R A C TThis study aimed to evaluate the kinetics of drying of Serjania marginata leaves, as well as to adjust different mathematical models to the experimental values of the moisture ratio. The Serjania marginata Casar leaves were harvested with initial moisture content of 2.03 ± 0,10 decimal dry basis., and submitted to drying process under controlled conditions of temperature (40, 50, 60 and 70 ºC), until the moisture content of 0.08 ± 0,02. Ten mathematical models were fitted to the experimental data and utilized to predict the drying process of agricultural products. Based on the obtained results, the mathematical model of Midilli best represented the kinetics of drying leaves of Serjania marginata. The increase in temperature promotes: an increased rate of water removal in Serjania marginata leaves during drying; the increase of the effective diffusion coefficient, and this relationship can be described through the Arrhenius equation, which presents an activation energy for the liquid diffusion during drying of 81.39 kJ mol -1 for Serjania marginata leaves; an increase in Gibbs free energy, while the enthalpy and entropy decrease.Palavras-chave: modelo de Midilli coeficiente de difusão propriedades termodinâmicas razão de umidade

“…This improvement may be attributed to the greater dry matter production (Table 1) and accumulation of macronutrients measured for C. ensiformis (Table 2) because of their proven ability to fix nitrogen in the soil and their contribution to integral agricultural production systems, which is responsible for growth and development of pepper plant. According to Tabaldi et al (2012), leguminous plants, C. ensiformis are adapted to conditions of low fertility and high temperatures, have the fast growing ability, are capable of producing large amounts of biomass in a short period of time, and are capable of uptake nutrients from deeper layers, ensuring a large residual effect for the culture.…”

Nitrogen (N) fixation is performed efficiently by leguminous plants, which can then be used as 'green manure' to reduce the need for synthetic fertilizer (especially N) and thus sustainably provide satisfactory crop yields with low production costs. The aim of this study was to determine the effect of intercropping with leguminous species used as cover crops on branch growth and nutrient cycling of pepper plants. The experiment was carried out in an indoor system with a randomized block design with four replicates. The treatments consisted of seven leguminous plant species which were planted as cover crops for black pepper plants: Canavalia ensiformis, Mucuna deeringiana, Mucuna pruriens, Cajanus cajan, Crotalaria juncea, Crotalaria spectabilis and the uncovered control. Samples of leaves and branches were harvested from flowering leguminous plants to quantify the production of dry matter. In addition, macro-and micro-nutrients content was measured in the legumes. The growth of the main branch of the pepper plants was measured at 30 and 60 days after the leguminous cover crops were cut. The leguminous plants, M. pruriens, C. ensiformis, C. cajan and C. juncea provided higher accumulation of nutrients and dry matter production in the pepper plants. At 60 days after cutting, intercropping with C. ensiformis supported more growth of pepper plants as determined by main branch measurements.

Serjania genus is native of Neotropics, from Mexico to Northern Argentina, and includes more than 230 species, most of them found in Mexico and Brazil. Although the genus is scarcely studied, the scientific literature and ethnobotanic information suggest that the extracts or fractions of these extracts have components with different biological properties. A bibliographic search in SciFinder and Scopus data carried out in April 2014 and using the keyword Serjania showed eighteen compounds belonging to different classes of natural products identified in seven species of the genus, namely: Serjania communis, S. triqueta, S. salzmanniana, S. grammatophora, S. cuspidata, S. yucatensis and S. caracasana. In this review we discuss the main biological activities of these eighteen natural compounds. The extracts or fractions of extracts of these seven plants described in the literature showed the following biological activities: analgesic, anti-inflammatory, antioxidant, antiprotozoal, anticancer, antibacterial, larvicidal, gastroprotective and insect repelent. Especially relevant is the anticancer activity of some fractions and plant extracts according to the criterion of The American National Cancer Institute for fractions and plant extracts. Of the fatty acids group found in the seeds of the Serjania species described in the literature, most are unsaturated, such oleic, arachidic, and eicosenoic. The latter represents 57% -70% of the total fatty acids content in the Serjania species studied.Keywords: Sapindaceae; Serjania; phytochemistry; biological activities; anticancer. ResumoSerjania é um gênero nativo do Neotrópico, presente desde o México até o norte da Argentina, com mais de 230 espécies, a maioria delas encontradas no México e no Brasil. Embora o gênero seja pouco estudado, os estudos científicos e as informações etnobotânicas descritas na literatura sugerem que extratos ou frações destas espécies podem ter componentes com diversas propriedades biológicas. O levantamento bibliográfico nas bases de dados Scopus e SciFinder realizado em abril de 2014, usando a palavra-chave Serjania, mostrou o registro de 18 compostos de diferentes classes de produtos naturais, distribuídos por sete espécies do gênero, a saber: Serjania communis, S. triqueta, S. salzmanniana, S. grammatophora, S. cuspidata, S. yucatensis e S. caracasana. Nesta revisão são discutidas as principais atividades biológicas destes 18 compostos naturais. Os extratos ou as frações dos extratos destas sete plantas descritas na literatura mostraram as seguintes atividades biológicas: analgésica, anti-inflamatória, antioxidante, antiprotozoária, anticâncer, antibacteriana, larvicida, gastroprotetora e repelente. Dentre as atividades biológicas, a mais importante, pelos critérios adotados pelo The American National Cancer Institute para frações e extratos vegetais, é a anticâncer. Os ácidos oleico, araquídico e eicosenoico foram os principais ácidos graxos encontrados nas sementes das espécies de Serjania descritas na literatura. O ácido graxo eic...
