Medicinal plants are widely used to treat various diseases, and in Brazil the plants Maytenus ilicifolia Mart. and Bauhinia candicans Benth are commonly used in popular medicine. However, there are a large number of compounds in plants which can produce alterations in genetic material, and this study was conducted to investigate any possible mutagenic and cytotoxic effects that M. ilicifolia and B. candicans infusions may have on the cell cycle and chromosomes. Infusions were prepared with in natura leaves to give two concentrations of infusions, one at the concentration normally used by the population in general and the other at 10 times this value (i.e. 3.5 and 35 mg/mL for M. ilicifolia and 0.465 and 4.65 mg/mL for B. candicans). Onion (Allium cepa L.)...

Microwave as an alternative to sample preparation in the foliar tissue silicon analysis of wood species for colorimetric determination
Provedor de dados: 190
Autores: Pereira, Claudia Mara; Hansel, Fabrício Augusto; Radomski, Maria Izabel; Verdeckin, Maisa Gottardo.
The aim of this work was to test the viability of microwave digestion for the colorimetric determination of silicon in foliar tissues of wood species. In the test, the correlation coefficient was 0.998 in the concentration range of 0.4 to 7 mg.g-1. Spiked cellulose samples were used and the recovery was high than 90 % in two tested concentrations (2 e 4 mg.g-1). The obtained coefficients of variation were equal to 4.2 % and 7.0 % for espinheira santa (Maytenus ilicifolia) and eucalipto (Eucalyptus benthamii), respectively. The microwave-induced digestion was compared to autoclave-induced digestion by interlaboratorial test, with relative errors smaller than 17 % in all tested samples (n=10). Based on these results, the microwave digestion of foliar tissues...

Enraizamento de miniestacas de espinheira-santa (Maytenus ilicifolia Mart. ex Reissek) em diferentes substratos

Pertencente à família Celastraceae, a espinheira-santa (Maytenus ilicifolia Mart. ex Reissek) é uma espécie medicinal nativa da região sul do Brasil, utilizadas no tratamento de gastrite e úlceras gástricas. Estudos sobre a produção de mudas por meio de estaquia demonstraram que esta espécie é considerada de difícil enraizamento. Objetivou-se, no presente trabalho, avaliar os efeitos de diferentes substratos no enraizamento de miniestacas de espinheira-santa. Miniestacas apicais foram coletadas a partir das brotações das minicepas de 10 meses de idade, mantidas em casa-de-vegetação e confeccionadas com 3 a 4cm de comprimento, mantendo-se duas folhas com a superfície reduzida à metade. O plantio foi realizado em caixas contendo areia e tubetes contendo...
