Fenologia reprodutiva e distribuição espacial de Oeceoclades maculata (Lindl.) Lindl. (Orchidaceae) em Cerrado do município de Mogi Guaçu, São Paulo, Brasil

Oeceoclades aculate (Lindl.) Lindl., an invasive orchid, was analyzed as to its reproductive phenology and spatial distribution, correlation between abundance of mature and immature individuals, and verifying these with microclimate patterns in the Cerrado (savanna-like vegetation) of Mogi Guacu, Sao Paulo State, Brazil. For the reproductive phenology 100 plants were followed and the distribution pattern was identified by the Morisita Index (MI) and the Variance Ratio/Average (R) in 20 plots of 20x10m, reduced to 10x10m afterwards. The phenology presented seasonality, with flowering from November to February, fructification from February to June, and dehiscence from June to July. Mature and immature individuals aggregated and correlated to each other, indicating dependence between the ontogenetic stages. The luminosity was the preponderant microclimatic factor in the allocation of plants. Seasonal climatic changes and intensity of anthropogenic disturbances seem to be more important for the establishment of the species than microclimate.

Análise estrutural em relictos de cerrado no parque estadual do Guartelá, município de Tibagi, estado do Paraná, Brasil

This study was accomplished in existing Cerrado's relicts at State Park Guartelá, Tibagi, PR (24°39'10S and 50°15'25W), which represent one of the last extreme-meridional remanescents of this type of formation. Fifty plots with dimensions of 5x5m were allocated for phyto-sociological analysis, including in the sample individuals with height ≥ 1 m, divided into two samples to evaluate the following strata: a) upper-plants with DAS ≥ 3 cm, and b) intermediate - plants with DAS <3cm. Moreover, in each plot, there were established sub-plots with dimensions of 1x1m for sampling the lower stratum, comprised by individuals with height <1m and >10cm. The complete survey found 1340 individuals distributed in 28 families, 66 genera and 115 species. The diversity index was higher for the mean component (H'=3.30), followed by the superior component (H'=3.09) and the inferior (H'=2.91). The frequent occurrence of bushes is a remarkable characteristic of the physiognomy of the areas inside the park and 82 % of the populations studied are distributed in aggregated standard. Because it is a marginal region of occurrence of cerrado vegetation, now under the influence of a subtropical climate, more humid and cold, compared to the core area of this biome, it is noted that these areas are characterized by a decrease in stature, richness and diversity of its flora. Nevertheless, they preserve typical species of the Brazilian Savannah; but, due to their distribution in relicts and been, in part, devastated, some are included in the red list of endangered plants in Parana state, which evidences the importance of conservation and management of these areas.

Controle de qualidade e obtenção de extratos de espécies vegetais do cerrado brasileiro com potencial etnofarmacológico

ANVISA (National Health Surveillance Agency) has published in recent years, laws that regulate the stages of the control of plants derivatives, including tests of macro and microscopic botanical identification, phytochemical determination, tests of authenticity and purity, microbiological testing, among other parameters. All the analytical procedures of plant drugs control required by law must be based on the Brazilian Pharmacopoeia, other Pharmacopoeias recognized by ANVISA or quality control guides of plant species published by the World Health Organization (WHO). This study aimed to evaluate some pharmacognostic, phytochemical screening and microbiological control of plant species of the Brazilian cerrado, which have indicated ethnopharmacological: Byrsonima intermedia (Bi), Bauhinia holophylla (Bh) and Myrcia bella (Mb). In addition, certain parameters were determined for obtaining extracts from plants sprayed and dried. These data are important to obtain new scientific information from Brazilian plants with therapeutic potential.
