Composição do óleo essencial de rubim (Leonurus sibiricus L. - Lamiaceae)

The essential oils are found in a great number of Lamiaceae family species, but few researches were carried out on this subject. This work had as a goal to identify the Leonurus sibiricus L. (rubim) essential oil composition. Rubim leaves and flowers in infusion are able to avoid vomit, diarrhea, and are also indicated in cold, cough, bronchitis and rheumatisms cases. In order to know what are the phytochemical compositions involved, it was used the gas chromatography techniques with mass spectrometry (GC-MS) as methodology. The results showed 70% volatility compound by trans-cariophylene, alpha-humulene and germacrene-D. Other substances like gamacadinene, beta-bourborene and alpha-copaene were found like compounds of this essential oil species.

O modelo 'hydrotime' pode descrever a resposta de sementes de feijão comum (phaseolus vulgaris l.) à temperatura e potenciais de água reduzidos

Germination parameters of the response to temperature and water potential from four common bean (Phaseolus vulgaris) lines based on thermal-time and hydrotime concepts were estimated to verify to what extent they can predict germination under different thermal and water conditions. The cultivars IPR Uirapuru and IAPAR 81 (drought-tolerant), and Grauna and Carioca (not tolerant) were used. The isothermal assays were performed in a temperature gradient block, and the assays with different osmotic potentials (PEG 6000) were performed in germination chambers. Seeds from drought-tolerant cultivars spent less time to germinate at supra-optimum temperatures than non-tolerant ones, and the cultivar Uirapuru (drought-tolerant) germinated faster in response to reduced Ψ and low temperatures. The parameter Ψb(50) did not discriminate between drought-tolerant and non-tolerant lines at the infraoptimum temperature range, but it can be used to identify drought-tolerant lines at high temperatures. In general, the hydrotime model reproduced the actual germination data relatively well, chiefly at higher temperatures. This study evidenced that the hydrotime model can be used to describe the germination of common bean seeds under reduced water potentials, and as a screening tool for drought-tolerant bean genotypes.
