CERNE , 2010,
Abstract: The Bignoniaceae family has 120 genera and 800 species with pantropical distribution, occurring mainly in the neotropics. About 32 genera and 350 species occur in Brazil, which is considered the center of diversity of the family. In Minas Gerais, some surveys indicate the occurrence of species such as Dolichandra unguis-cati, Fridericia speciosa and Handroanthus chrysotrichus. Lavras studies show 58 species. The municipality is located in a transition zone between savanna and semideciduous forest, with rugged terrain, which promotes a diversity of vegetation physiognomy. The objective was to catalog the species of native and exotic Bignoniaceae of Lavras, Minas Gerais, besides the elaboration of an identification key for them. Data were collected from all herbarium specimens with record collection in the city incorporated in the Herbarium ESAL; species cited in phytosociological studies of the county and registration of ornamental species found in parks, gardens and nurseries of the city were also raised. The specimens were identified in situ, by comparisons, consultations with specialists and specialized taxonomic literature. Fifty eight species (51 native and seven exotic) were found, distributed in 21 genera, of which Jacaranda (10 species) was the most common, followed by Fridericia (8 species) and Handroanthus (7 species). Among the ornamental species stood out Handroanthus impetiginosus (Purple-ipe) and Handroanthus serratifolius (Yellow-ipe). The number of species was superior to other localities, the largest similarity observed was with species of Itacolomi State Park, Minas Gerais.

Abstract: the angular coefficient of the linear regression analysis and the mann-kendall's coefficient were used to analyze the monthly climatic trends of the maximum and minimum air temperatures, sunshine and water vapor content, on selected locations in the state of minas gerais. both statistical tests were applied in three different periods, one, from 1961 to 2004, and the other ones at intervals separeted by the discontinuity point detected by the standard normal homogeneity test (snht). the most relevant results indicated that in minas gerais the maximum and minimum air temperatures increased in the period 1960-2004, between 1,3oc and 3,9oc, but this behavior was generally not gradual, being associated with the discontinuity occurring mostly in the 1990's. most of the significant increase of the maximum temperature was centered between september and december. the dominance of positive trend for water vapor was consistent with the increase in the observed extreme air temperature. it was observed, among the low significant trends of sunshine, a persistence decline from the 1960's until the mid-1990's.

Abstract: The aim of the present work was to carry out a bioguided isolation of antiviral chemical constituents from an ethanol extract of leaves from Arrabidaea pulchra (Cham.) Sandwith (EEAPL) that had shown in vitro activity in a previous screening using DNA and RNA viruses. The activity of EEPAL was evaluated against the DNA viruses Human herpesvirus 1 (HSV-1) and Vaccinia virus Western Reserve (VACV-WR) as well as against the RNA viruses Murine encephalomyocarditis virus (EMCV), and Dengue virus 2 (DENV-2) by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) colorimetric assay. Cytotoxicity was determined in LLCMK 2 and Vero cells and the Selectivity Indexes (SI) were calculated. The most potent effect was observed against DENV-2 (EC 50 46.8 ± 1.6 μg mL ?1; SI 2.7). For HSV-1 and VACV-WR EC 50 values > 200 μg mL ?1 were determined, while no inhibition of the cytopathic effect was observed with EMCV. Bioguided fractionation of EEAPL by partition between immiscible solvents followed by chromatography over a Sephadex LH20 column afforded two arylpropanoid glycosides, verbascoside ( AP 1) and caffeoylcalleryanin ( AP 2), along with a terpenoid, ursolic acid ( AP 3). AP 1 and AP 3 exhibited similar anti-DENV-2 profiles, with SI values of 3.8 and 3.1, respectively, while AP 2 was the most effective anti-DENV-2 constituent, with a SI of 20.0. Our results show that A. pulchra leaves ethanol extract (EEAPL) affords compounds with antiviral activity, mainly against DENV-2.
