Jurema-Preta (Mimosa tenuiflora [Willd.] Poir.): a review of its traditional use, phytochemistry and pharmacology

Mimosa tenuiflora Willd., popularly known as jurema-preta, is an arboreal species of great importance for the brazilian Northeast due to its uses as a medicinal plant and in the restoration of degraded soils. No information is available in the Rules for Seed Analysis and the Instructions for Seed Analysis of Forest Species regarding ideal conditions for of this species. Thus, this study aimed at evaluating the influence of pre-germination treatments, in addition to verifying the germination performance at different temperatures and in different substrates. In both experiments, four replicates of 25 seeds were used for each treatment. In experiment I, seeds were submitted to the following methods for overcoming dormancy: witness -Intact seeds (T1) immersion in water at 100 °C for 1 (T2), 2 (T3), 3 (T4), 4 (T5), 5 (T6) and 6 min (T7), immersion in concentrated sulfuric acid for 1 (T8), 4 (T9), 7 (T10), 10 (T11) and 13 min (T12), scarification on sandpaper n° 80 (T13) and lopping in the region opposite the micropyle (T14). In experiment II, seed germination was evaluated in four types of substrates: between sand, paper on, paper roll and between vermiculite and at six different temperatures: 20, 25, 30, 35, 40 °C and alternating between 20 and 30 °C. Immersion in hot water for 1, 2, 3, 4, 5 and 6 min, sulfuric acid treatment for 10 and 13 min, sand paper and lopping were the most appropriate treatments to overcome seed dormancy. The seed germination of M. Tenuiflora should be carried out at 25 °C on paper roll substrate. Key words: Jurema-preta. Seed germination. Caatinga. Seed analysis. ResumoMimosa tenuiflora Willd. conhecida popularmente como jurema-preta é uma espécie arbórea de grande importância para o Nordeste brasileiro pela sua multiplicidade de usos, como na medicina popular, recuperação de solos degradados e fixação de nitrogênio. Ainda não há informações disponíveis nas Regras para Análise de Sementes e nas Instruções para Análise de Sementes de Espécies Florestais com relação às condições ideais para condução do teste de germinação desta espécie. Dessa forma, objetivou-se avaliar a influência da aplicação de tratamentos pré-germinativos, além de verificar o desempenho da germinação em diferentes temperaturas e substratos. Em ambos os experimentos foram utilizados quatro repetições de 25 sementes para cada tratamento. No experimento I, as sementes foram submetidas aos seguintes métodos para superação de dormência: testemunha -sementes intactas (T1), imersão em água a 100 °C por um (T2), dois (T3), três (T4), quatro (T5), cinco (T6) e seis minutos (T7), imersão em ácido sulfúrico concentrado por um (T8), quatro (T9), sete (T10), dez (T11) e treze minutos (T12), escarificação em lixa n° 80 (T13) e desponte na região oposta a micrópila (T14). No experimento II, a germinação das sementes foi avaliada em quatro tipos de substratos: entre areia, sobre papel, rolo de papel e entre vermiculita e em seis temperaturas: 20 °C, 25 °C, 30 °C, 35 °C, 40 °C e alternada 20-30 °C. A imersão em água quente por 1,...

S u m m a r yBased on epidemiologic surveys conducted in [2007][2008][2009][2010][2011][2012][2013], an increase in the consumption of psychoactive substances has been observed. This growth is noticeable in Europe and in Poland. With the 'designer drugs' launch on the market, which ingredients were not placed on the list of controlled substances in the Misuse of Drugs Act, a rise in the number and diversity of psychoactive agents and mixtures was noticed, used to achieve a different state of mind. Thus, the threat to the health and lives of people who use them has grown. In this paper, the authors describe the phenomenon of the use of plant psychoactive substances, paying attention to young people who experiment with new narcotics. This article also discusses the mode of action and side effects of plant materials proscribed under the

Recebido:xx xxxxxx xxxx Aceito: xx xxxxx xxxx Identificação da fração antimicrobiana do extrato da Mimosa tenuiflora ResumoNa pesquisa de moléculas e compostos antifúngicos com baixa periculosidade, faz-se relevante a ação inespecífica destes, pois há possibilidade de se tornarem inativos devido ao desenvolvimento de resistência. Com o objetivo de aumentar as alternativas para o controle de Curvularia inaequalis e Colletotrichum gloeosporioides, cascas de M. tenuiflora foram coletadas e processadas para a obtenção do extrato aquoso, que em seguida foi fracionado através de cromatografia em coluna, cromatografia em camada delgada, e analisado através de cromatografia líquida de alta eficiência (CLAE), para identificação dos compostos ativos. Com as fases obtidas, realizaram-se testes de germinação com C. inaequalis. Na fase "um" foi identificada a presença dos flavonoides catequina e apigenina. Essa fase apresentou atividade de degradação ou inibição da formação da camada de quitina de C. inaequalis e as outras fases não mostraram atividade nas concentrações avaliadas. A catequina também apresentou inibição da germinação de C. inaequalis. Quando avaliado o extrato bruto sobre a germinação de C. gloeosporioides, todas as concentrações foram eficientes na inibição da germinação, sendo que a partir de 4 mg.mL -1 a inibição foi de 100%. A fase "um" e a catequina inibiram a germinação de C. inaequalis e o extrato bruto inibiu, de forma semelhante à fase "um", a germinação de C. gloeosporioides. Palavras-chave: Antifúngicos, Compostos ativos, Flavonoides Identification of the antimicrobial fraction of Mimosa tenuiflora extract AbstractIn the search of molecules and antifungal compounds with low hazard, it is important the compound inespecific action, since there is a possibility of inactivity due to the resistance development. In order to increase the alternatives for the Curvularia inaequalis and Colletotrichum gloeosporioides control, husks of M. tenuiflora were collected and processed for obtaining the aqueous extract, which was then fractionated by column chromatography, thin layer chromatography and analysed by high-performance liquid chromatography (HPLC), aiming the identification of active compounds. After obtaining the phases, germination tests were carried out with C. inaequalis. The phase "one" showed the presence of flavonoids catechin and apigenin. This phase presented degradation or inhibition of chitin layer formation in C. inaequalis and the other phases presented no activity for the evaluated concentrations. Catechin also presented inhibition of C. inaequalis germination. For the evaluation of the effect of crude extract on C. gloeosporioides germination, all concentrations were effective in inhibiting germination, and when 4 mg.mL -1 or higher concentrations were used, the inhibition was 100%. The phase "one" and the catechin inhibit the C. inaequalis germination and the crude extract inhibited, similarly to phase "one", the germination of C. gloeosporioides.
