“…The structure of compound 11 was elucidated as coumarin using NMR 1 H and 13 C spectral data compared with the literature (Sun et al, 2007;Canuto et al, 2010). The ayapin was previously isolated from extracts of aerial parts and roots of the plant (Bohlmann et al, 1983).…”

Organic extracts from leaves plus branches plus inflorescences of Ageratum fastigiatum (Gardner) R. M. King & H. Rob., Asteraceae, were fractionated through classic chromatography. The steroids stigmasterol, chondrillasterol and campesterol were isolated from hexane extract. The triterpenes lupeol, taraxasterol, α-amyrin, β-amyrin, pseudotaraxasterol, lupeol acetate and α-amyrin acetate were isolated from ethyl acetate extract. Steroids and triterpenes were identified by GC-MS. The coumarin ayapin was isolated from ethanol extract and identified by NMR. Essential oils of the fresh leaves and fresh inflorescences were obtained by hydrodistillation and analyzed for GC-MS. The main components in both essential oils were α-pinene, limonene and germacrene D.

“…Vários compostos já foram isolados e identificados de A. cearensis, incluindo: ácido protocatecuico, cumarinas, flavonóides (isocampferídeo, campferol, afrormosina, 4'-metoxifisetina e quercetina) e glicosídeos fenólicos (amburosídeo A e B),entre outros (Bravo et al,1999;Canuto et al, 2010). Os glicosídeos fenólicos encontrados em A. cearensis, como o amburosídeo mostrou atividade antimalárica, antiprotozoária, antifúngica e antibacteriana in vitro (Bravo et al,1999).…”

RESUMO:A suinocultura é uma atividade pecuária bem consolidada no Brasil. Por outro lado a colibacilose neonatal, cujo patógeno é Escherichia coli, pode diminuir a produtividade nas granjas e causar prejuízos aos produtores. O tratamento baseia-se na utilização de drogas antimicrobianas. Todavia, o uso indiscriminado dessas substâncias tem levado a seleção de cepas resistentes. Diante disso, a busca por alternativas terapêuticas, como as plantas medicinais, tem se tornado cada vez mais comum. Dessa maneira, objetivou-se determinar a atividade antimicrobiana de cinco extratos etanólicos de plantas do bioma caatinga: Amburana cearensis (Fr. Allem) A.C. Smith, Encholirium spectabile Mart., Hymenaea courbaril L, Neoglaziovia variegata Mez e Selaginella convoluta Spring frente a 43 isolados de Eschericha coli coletados de suínos. Para o teste de sensibilidade in vitro foi realizada a técnica da Concentração Bactericida Mínima (CBM) pelo método da microdiluição em microplaca. Os extratos apresentaram atividade antimicrobiana nas seguintes médias 138,75 175,28, 128,36, 127,71 e 129,33 μg/mL, respectivamente. Essa atividade antibacteriana pode estar relacionada a ação de metabólitos secundários presentes nos extratos dessas plantas. Dessa forma, nosso estudo pode contribuir para o desenvolvimento de alternativas terapêuticas no tratamento de infecções, como a colibacilose neonatal em suíno, bem como para o conhecimento acerca das plantas medicinais da Caatinga.Palavras Chave: Suinocultura; Plantas Medicinais, Metabólitos secundários. ABSTRACT: Antimicrobial activity in vitro extracts from caatinga plants in isolatedEscherichia coli from pigs. Swine production is a well-established livestock activity in Brazil. On the other hand, the Neonatal Colibacillosis, whose pathogen is Escherichia coli, can decrease the productivity on farms and cause losses to producers. The treatment of the disease is based on the use of antimicrobial drugs. However, the free use of these substances has led to the selection of resistant strains. Thus, the search for alternative therapies such as medicinal plants has become becoming increasingly common. In this context, we aimed to determine the antimicrobial activity of ethanol extracts of five plants from the caatinga biome: A. cearensis (Fr. Allem) AC Smith, Encholirium spectabile Mart, Hymenaea courbaril L, Neoglaziovia variegata Mez and Selaginella convoluta Spring in face of isolates of Eschericha coli collected from pigs. For the in vitro susceptibility testing, the method of Minimum Bactericidal Concentration (MBC) was chosen The extracts showed antimicrobial activity in the following averages 138.75 175.28, 128.36, 127.71 and 129.33 mg / mL, respectively. This antibacterial activity could be related to the action of secondary metabolites in the extracts of these plants. Thus, the current study can contribute to the development of alternative therapies for the treatment of infections such as swine Colibacillosis Neonatal, as well as to the knowledge of Caatinga medicinal plants

Phytochemical Profile of Seed Extracts of Plants Typical of the Brazilian Semiarid and their Potential Application in Brackish Water Desalination

The phytochemical profile of typical seeds from semiarid areas of Bahia was explored. The desalination capacity of the seeds discovered in previous studies considered the seeds potentially suitable for desalination of water. Coals composed of crushed seeds of umbu (Spondias tuberosa Arr. Cam.) and umburana (Amburana cearensis A. C. Sm.) were prepared by heating at 250 o C. As the desalination process using these materials involves ion exchange besides adsorption, it became necessary to study their chemical composition to check the possibility of transferring undesirable chemical species to the water during the contact between material and water. None of the tested metabolites were found in umbu coal, which enabled its use in desalination. However, the presence of coumarin and alkaloids in the umburana seeds coal indicated that this material is not suitable for that use.
