Abstract: due to the economic importance of the wood of mimosa l. species in northeastern brazil's caatinga and to the fact that mimosa ophtalmocentra mart. ex benth. ("jurema-de-imbira") is confused with mimosa tenuiflora (willd.) poir. ("jurema-preta") and vice versa, this research aimed to present new data related to the anatomy and basic density of the wood of both species; to contribute to the taxonomic study for differentiating them; to identify anatomical characters of the wood relating them to the caatinga environment; and to present the energetic potential that they possess. the anatomical study and wood density determination were carried out with samples at dbh level and with two branches of individuals within the municipalities of serra talhada and sertania (pernambuco). the species both differed in bark type, color of heartwood and sapwood, besides the different anatomical characteristics found in the wood. mimosa ophtalmocentra has distinct growth layers consisting of parenchyma lines containing crystals, scarce parenchyma and smaller quantity of rays. mimosa tenuiflora, on the other hand, also has growth layers, but without crystals, axial parenchyma vasicentric, confluent and in bands, and greater percentage of rays. both species have some wood elements with anatomical characteristics typical of representatives of mimosa, contributing therefore to a better taxonomic understanding of the genus. based on wood anatomical parameters and elevated basic density (> 0.84 g/cm3), the conclusion was reached that both species have great perspectives for the production of fuel alcohol and charcoal since juvenile wood age. because mimosa ophthalmocentra has scarce parenchyma and fewer rays, it shows greater energetic potential than mimosa tenuiflora.

Abstract: Objetivou-se avaliar o efeito do diametro do caule na desidrata o, composi o química e disponibilidade de feno da Jurema preta (Mimosa tenuiflora). As plantas estavam com média de 3 metros de altura e em final de flora o. Foram selecionados caules representativos nos diametros 5, 6, 7, 8 e 9mm, os quais foram cortados, separados em caule e folhas e submetidos ao processo de desidrata o que consistiu na secagem em estufa de circula o de ar for ada a uma temperatura de 65°C até peso constante. A curva de desidrata o foi obtida em fun o dos intervalos de tempo de pesagem. Para as demais variáveis utilizou-se o delineamento inteiramente casualizado, com cinco tratamentos e cinco repeti es. A desidrata o de caule e folhas teve resposta linear com plat , maior para diametros de 5mm cuja perda foi de 0,02g de água/g matéria seca ao final de 15,84 horas no caule, e de 0,01g de água/g MS na folha a partir 13,48 horas. Os teores de proteína bruta do caule diminuíram e os de fibra em detergente neutro e fibra em detergente ácido aumentaram com o diametro do caule, mas n o houve influência na composi o química da folha. Se o objetivo for qualidade, os caules de Jurema preta devem ser cortados com diametros inferiores a 6mm; se o objetivo for quantidade o diametro deve ser de 7 a 9mm; se a finalidade for adequar qualidade e quantidade, recomenda-se cortar os caules ao atingirem 6mm de diametro. The objective of this work was to evaluate the effect of stem diameter in branch dehydration, chemical composition and hay production in Jurema preta (Mimosa tenuiflora). The selected plants were about three feet high and were in the end of blooming. Representative branches were selected with 5, 6, 7, 8 and 9 mm diameters, which were sliced and separated into stems and leaves and submitted to the dehydration process. It consisted of drying in the forced air circulation stove at a 65°C temperature until the constant weight was reached. The dehydration curve was obtained according to the weighing time intervals. The other variables used a completely randomized design with five treatments and five replications. The stem and leaves dehydration had a linear response with plateau, being greater at 5mm, with 0.02g water/g DM in the stems after 15.84 hours and 0.01g water/g DM in the leaves after 13.48 hours. The stem CP decreased and the NDF and ADF increased with the diameter of the branch, but it did not influence the leaf’s chemical composition. If the goal is branch quality in Jurema preta, they should be cut with diameters smaller than 6 mm; if the goal is quantity, w

Abstract: Genotoxic effects of Mimosa tenuiflora (Willd.) Poir, Fabaceae, were investigated by using both micronucleus test and bacterial reverse mutation assay in Salmonella typhimurium TA97, TA98, TA100, TA102 respectively. In respect of Ames test results show that the extract does not induce mutations in any strains of Salmonella typhimurium tested since the mutagenicity index is less than 2. In the antimutagenic effect was observed that the extract at the concentrations tested significantly decreased the mutagenicity index of all strains tested which characterized the extract as antimutagenic in these conditions. In the micronucleus test in vivo, we observed that the concentrations used did not induce an increase in the frequency of micronucleus in normochromatic erythrocytes of mice. Therefore, we concluded that the extract of M. tenuiflora is not mutagenic in the absence of exogenous metabolizing system and does not induce an increase in the frequency of the micronucleus characterized as an agent not mutagenic in these conditions. Further studies of toxicity need to be made to the use of this plant in the treatment of diseases to be stimulated.

Abstract: because of some catastrophic events which occurred in mexico during the 1980 decade, the utilization of "tepescohuite" bark against skin wounds and burns was popularized. the media manipulated the lack of available information about its medical properties and gave erroneous information to the society propagating a lot of myths. therefore, the aim of this paper is to determine its taxonomic identity and to study the distribution, bark and wood anatomy of this species, and to determine its actual and historic uses, and the compilation of the information about bark pharmacology and toxicity. its taxonomic identity is established as mimosa tenuiflora (willd.) poir. (fabaceae-mimosoideae). it blooms and fructifies from november to june, occurring in mexico (the states of oaxaca and chiapas), guatemala, honduras, el salvador, nicaragua, panama, colombia, venezuela and brazil, at altitudes of 0-1110 (-1520) m. in mexico, it is found in dry forests, thorny thickets, pinus and pinus-quercus forests, and in m. tenuiflora pure thickets, along roads and in resting or abandoned culture lands. this species has an aggregate distribution in the forests and a uniform one in the thickets. it presents a mean density of 9 individuals per m2, with 0.45 of frequency per quadrat and 1.69 m2 of mean coverture, and it has a wide range of tolerance to climatic and edaphic factors, confirming their invasive character. regionally, the wood is used as fuel and fence construction, and against skin wounds and burns (bark tea, powder and/or ointment), and diverse products, such as shampoos, creams, capsules, soaps, etc., are commercialized. the bark is wrinkled, reddish-brown to grey, fibrous texture, 0.5-1.5 mm thick, resinous and with an astringent odor and flavor, and with a great quantity of tannins. the wood presents extremely short vessel elements, with alternate areolate punctuations, and simple perforated plates, vasicentric axial parenchima, confluent stripes, uniseriated rays, extremely
