“…It was expected that the ash content would increase gradually from one lot to another, however, comparing the periods of greatest changes in temperature and rainfall, i.e., rainy season and prolonged dry season, lot 1 and lot 3, respectively, a significant (p < 0.05) increase was observed between them. During the dry season, sediment deposition in soil is not affected by leaching due to rain, favoring greater permanence of minerals in the soil and consequently in the parts of the plants (Amarante et al, 2011), which explains the highest ash content in the seeds from the prolonged dry season.…”

Composição química da semente da faveleira (Cnidoscolus phyllacanthus) em diferentes períodos sazonaisNa vegetação da caatinga a Cnidoscolus phyllacanthus, popularmente conhecida como favela ou faveleira, destaca-se por ser uma planta altamente resistente a seca e de alto teor nutricional, apresentando diversas aplicações. O objetivo deste trabalho foi avaliar a influência de diferentes períodos sazonais na composição química da semente da faveleira da região Seridó/RN. As sementes, separadas em 3 lotes por períodos sazonais diferentes (lote 1 -época chuvosa; lote 2 -estiagem inicial; lote 3 -estiagem prolongada), foram trituradas e analisadas quanto aos teores de umidade, cinzas, lipídios, proteínas e carboidratos. Verificou-se que as sementes da faveleira apresentaram predominância de lipídios e de proteínas. Na análise de umidade observou-se diferença significativa (p < 0,05) entre todos os lotes, o teor de cinzas foi significativamente (p < 0,05) menor no lote 1 (4,67 ± 0,18) quando comparado ao lote 3 (4,96 ± 0,08), na análise de proteínas o lote 3 (30,42 ± 1,63) apresentou o maior teor e diferiu significativamente (p < 0,05) dos demais. Quanto aos lipídios houve diferença significativa (p < 0,05) entre os lotes, Cnidoscolus phyllacanthus, popularly known as favela or faveleira, is a species of the caatinga vegetation highly resistant to drought, with high nutritional content, and having several uses. The objective of this work was to evaluate the influence of different seasons on the chemical composition of faveleira seeds in the region of Seridó/RN. The seeds collected in different seasons were separated into 3 lots (lot 1 -rainy season; lot 2 -initial dry season; lot 3 -prolonged dry season), ground, and analyzed for moisture, ash, lipids, protein, and carbohydrates. The chemical analysis the seeds showed predominance of lipids and proteins. The results showed that moisture was significant different (p < 0.05) between all the lots; the ash content in lot 1 was significantly (p < 0.05) lower (4.67 ± 0.18) than lot 3 (4.96 ± 0.08); and protein content was highest in lot 3 (30.42 ± 1.63) and significantly (p < 0.05) different from the others. There was a significant difference (p < 0.05) for lipids between the lots, with lot 2 showing the lowest content (21.57 ± 0.37). Significant difference (p < 0.05) was also found for carbohydrates between the lots, with lot 1 (14.37 ± 1.83) having the lowest content and lot 2 (39.17 ± 0.52) the highest content. The differences observed between the lots are attributed to the harvest of the seeds in different seasonal periods. The results show that the seasonal period influences the nutritional value of faveleira seeds, and that better forms of use need to be identified according to the period of harvesting.

“…This species can occur in several types of habitat, being found onshore or in water-saturated soils (Amarante et al, 2011). This macrophyte is distributed in the tropics (Mayo et al, 1997) and has considerable importance in the formation of riverbanks and white water streams, forming extensive clonal populations by sprouting from underground and submerged stems (Amarante et al, 2011). Seed length ranges from 33-51 mm (mean 39.53 mm) and width ranges from 23-33 mm (mean:…”

The role of Lithodoras dorsalis (Siluriformes: Doradidae) as seed disperser in Eastern Amazon

Ichthyochory is an important process responsible for the high diversity of plant species in tropical flooded forests. Thus, this study aimed to investigate the role of a catfish species, Lithodoras dorsalis, as seed disperser in the flooded forests at the Amazon River mouth, Brazil. Analyzing the stomach contents of 371 individuals of Lithodoras dorsalis, the Germination Potential (GP%) and Germination Speed Index (GSI) of seeds that were removed intact were investigated. This allowed us to evaluate the germination performance of two important species of plants in Amazonia, Euterpe oleracea (Açaí) and Montrichardia linifera (Aninga), after passage through the digestive tract of this catfish species. Given that digestion by L. dorsalis reduced the germination viability of M. linifera and that seeds were often destroyed during consumption, we suggest that L. dorsalis may have a limited role as seed disperser of M. linifera and instead mostly act as seed predator. However, for the species E. oleracea, L. dorsalis was a potential disperser, since the performance of germination of these seeds was improved after digestion. In addition, the number of seeds consumed was directly proportional to the catfish's body size, reinforcing the role of doradids as potential seed dispersers in tropical forests. Keywords

RESUMO: O uso de plantas medicinais no tratamento de doenças é uma estratégia antiga utilizada por praticamente todas as populações do mundo, e, embora novos antibióticos tenham sido desenvolvidos para o controle de micro-organismos infecciosos, às vezes são ineficazes. Diversos extratos de plantas medicinais têm efeitos antimicrobianos, principalmente quando associados à antibióticos de uso clínico, representando alternativa terapêutica para doenças infecciosas. Montrichardia linifera, conhecida popularmente como aninga, é espécie macrófita, aquática emergente de hábito herbáceo, pertencente a família Araceae e ocorre em áreas alagáveis. A utilidade farmacológica desta espécie é diversificada tendo sido relatada como cicatrizante, antirreumático, antidiurético e expectorante. Devido à relevância no campo etnofarmacológico, ampla utilização na medicina popular e escassez de trabalhos relacionados à atividade antibacteriana desta espécie, objetivou-se com este trabalho avaliar a atividade antibacteriana de extratos alcoólicos de folhas de Montrichardia linifera, coletadas na margem do rio Igaraçu, Parnaíba-PI. O extrato foi testado em oito cepas de bactérias: Staphylococcus aureus, Staphylococcus epidermidis, Enterococcus faecalis, Escherichia coli, Klebsiella pneumoniae e Pseudomonas aeruginosa. Foram utilizadas as técnicas de verificação da formação de halos de inibição e determinação das concentrações inibitórias e bactericidas mínimas. Os testes antibacterianos evidenciaram como principais resultados que o extrato metanólico seco (EMS), extrato metanólico fresco (EMF), e o extrato etanólico seco (EES), apresentaram ação antibacteriana, enquanto o extrato etanólico fresco (EEF) não apresentou atividade para as bactérias testadas. O EMS foi o mais eficiente, inibindo o crescimento bacteriano na concentração de 200 μg/mL para E. faecalis, 400 μg/mL para S. aureus, 400 μg/ mL para S. epidermidis e 2.000 μg/mL para P. aeruginosa. O EMF obteve CIM de 2.000 μg/mL para E. faecalis e EES obteve CIM de 250 μg/mL para E. faecalis. Os resultados demonstraram que M. linifera constitui fonte eficiente de compostos bioativos antibacterianos. Os estudos sobre as propriedades farmacológicas de plantas da família Araceae são escassos, e os resultados deste trabalho são pioneiros em relação a atividade antibacteriana desta espécie.

For a long time, medicinal herbs have been used in the treatment of diseases by almost all populations in the world, and although new antibiotics have been developed for the control of infectious micro-organisms, they are sometimes ineffective. Many herbal extracts have antimicrobial effects and represent a potential alternative therapy for infectious diseases, especially when associated with the clinical use of antibiotics. The Montrichardia linifera, popularly known as Aninga, is a robust, herbaceous, emergent aqua...
