“…The leaves are used in cataplasms, with hot butter and olive oil as a moisturizing agent. 5 In recent years, bacterial resistance to antibiotics has become a serious public health problem that concerns almost all antibacterial agents. Efflux pumps are integral proteins of the bacterial membrane and are recognized as a major cause of bacterial resistance since they extract antibiotics from the cell.…”

Recebido em 13/12/10; aceito em 21/3/11; publicado na web em 5/5/11From the aerial parts of Sidastrum micranthum (A. St.-Hil.) Fryxell (Malvaceae) were isolated m-methoxy-p-hydroxy-benzaldehyde, o-hydroxy-benzoic acid, acacetin, quercetin, 7,4′-Di-O-methylisoscutellarein, genkwanin and tiliroside. These compounds were identified by data analyses of spectroscopic methods. Although acacetin and 7,4′-Di-O-methylisoscutellarein did not display relevant antibacterial activity (MIC = 256 μg/mL), they modulated the activity of antibiotics, i.e. in combination with antibiotics at 64 μg/mL (¼ MIC), a two-fold reduction in the MIC was observed for norfloxacin and ethidium bromide; regarding tetracycline and erythromycin a two-fold reduction in the MIC was observed only with 7,4′-Di-O-methylisoscutellarein.

“…Certain species native to the Caatinga can be used for a variety of purposes, such as urban landscaping (Dantas and Souza, 2004), the recovery of riparian vegetation (RibeiroFilho et al, 2009) and pharmaceutical and medicinal applications (Agra et al, 2007). These species include Anadenanthera macrocarpa (Benth.)…”

Germinative metabolism of Caatinga forest species in biosaline agriculture

et al. 2014

-The production of seeds and seedlings by these species is of utmost importance to prevent a loss of biodiversity of the Caatinga, a unique and exclusively Brazilian biome. Biosaline agriculture is conducted over a range of salinity levels in groundwater and/or in soils. The current study evaluated the application of biosaline agriculture to Anadenanthera macrocarpa, Myracrodruon urundeuva, Aspidosperma pyrifolium and Erythrina velutina by examining the germinative metabolism of seeds subjected to different electrical conductivities (ECs) of NaCl solutions and biosaline water. The seeds were germinated in biosaline water (4.94 dS.m -1) and in NaCl solutions with ECs of 0, 2, 4, 6, 8, 10, 12, 14, 16 and 18 dS.m -1 at 25 °C, 12-h photoperiod. The kinetic variables of germination were assessed, and the seeds and seedlings were assayed for reserve biomolecules, proline content and antioxidant enzyme activity. The seeds were highly tolerant to salinity, with germination-limiting ECs above 12 dS.m -1. Although high EC promoted alterations in seed metabolism that enabled salinity tolerance, seedling production was indicated with ECs no higher than 6 dS.m . These results demonstrated that Caatinga seedling production is viable through biosaline agriculture beucause the groundwater salinity of this region is within the tolerance levels of the seeds. . Embora, alta CE promova alterações no metabolismo sementes, permitindo tolerância à salinidade, a produção de mudas é indicada em CE inferior a 6 dS.m -1 . Assim, a produção de mudas da Caatinga é viável através da agricultura biossalina, pois as águas subterrâneas da região apresentam-se dentro deste nível.Termos de indexação: enzimas antioxidantes, germinação, mobilização de reserva, estresse salino.

“…In the states of Paraíba (Alves & Nascimento 2010, Agra et al 2007) and Piauí (Franco & Barros 2006) Brazil, I. asarifolia is popularly known as a medicinal plant and is used in the treatment of dermatological diseases, used to wash the affected areas. In studies conducted in Nigeria, I. asarifolia showed antioxidant (Ene-OjoAtawodi & Onoalapo 2010), analgesic and anti-inflammatory action (Lawal et al 2010, Jegede et al 2009 With the aim to determine if the tremorgenic toxin of Ipomoea asarifolia is eliminated in milk, three groups of Swiss female mice received, immediately after giving birth until weaning, a ration containing 20% or 30% of dry I. asarifolia.…”

RESUMO.-[Eliminação da toxina tremorgênica de INTRODUCTIONIpomoea asarifolia R. et Schult. (common name: salsa), family Convolvulaceae, is a plant native to South and Central America. In Brazil it is very common in the Amazon region, in the Northeast, and along the coast, from northern Brazil to the southern states of Rio de Janeiro and São Paulo (Kissmann & Groth 1992). I. asarifolia is a tremorgenic plant that causes poisoning in sheep (Döbereiner et al. 1960, Guedes et al. 2007), goats (Döbereiner et al. 1960, Medeiros et al. 2003, Guedes et al. 2007), cattle (Döbereiner et al. 1960, Barbosa et al. 2005) and buffalo (Barbosa et al. 2005). Clinical signs caused by I. asarifolia are similar than those caused by the indole-diterpene mycotoxins produced by different fungi (di Menna et al. 2012, Cawdell-Smith et al. 2010, but the tremorgenic toxin of the plant is unknown.In With the aim to determine if the tremorgenic toxin of Ipomoea asarifolia is eliminated in milk, three groups of Swiss female mice received, immediately after giving birth until weaning, a ration containing 20% or 30% of dry I. asarifolia. All the offspring of the females that received 20% or 30% I. asarifolia showed tremors 2-4 days after birth. The offspring of the females that received 20% I. asarifolia recovered 4-7 days after weaning. The offspring of the females that received 30% of the plant in the ration died while showing tremors before weaning or up to two days after weaning. It is concluded that the tremorgenic compound of I. asarifolia or its toxic metabolites are eliminated in milk, and that lactating mice may be used as a model for the determination of the toxic compound(s) in this plant.
