Antioxidant activity of jacaranda decurrens Cham. Repositório Alice
CARVALHO, C. A.; LOURENÇO, M. V.; BERTONI, B. W.; FRANÇA, S. C.; PEREIRA, P. S.; FACHIN, A. L.; PEREIRA, A. M. S.; MORAES, R. M.; CERDEIRA, A. L..
Many diseases and related degenerative processes including heart, câncer and Parkinson diseases are associated with rcactive oxygen species (ROS). In an effort Io preveni diseases, search for com-pounds with antioxidant activity hás been a major interestof dif-ferent research groups in natural products research. The objective of this research was to investigatethe antioxidant activity of EtOH leaf extract ofjacarando decurrrens and its fractions using the 2,2-diphenyl-2-picrylhydrazyl hydrate (DPPH) assay [lJ, that uses s pé ciro me t ric method to determine radical scavenging activity, Rutinattheconcçntrationof l.Omg-L was used as the standard. Our results ha vê shown lhat crude extract and fractions had anti-oxidant activities mainly if tested at...

Floral visitors and reproductive strategies in five melittophilous species of Bignoniaceae in Southeastern Brazil BABT
Yanagizawa,Yuriko A. N. Pinto; Maimoni-Rodella,Rita de Cassia Sindrônia.
In order to evaluate the pollination strategies of Bignoniaceae, the floral biology and the floral visitors in five species, three cerrado shrubs (Arrabidaea brachypoda (DC.) Bor., Jacaranda decurrens Cham., and Jacaranda oxyphylla Cham.), and two lianas from the border of a semideciduous seasonal forest (Arrabidaea samydoides (Cham.) Sandw., and Arrabidaea triplinervia H. Baill.) were studied in Botucatu, São Paulo State, Southeastern Brazil. The flowering periods were partially overlapping, especially between species in the same habitat. All the five species were functionally allogamous, melittophilous, nototribic and mainly pollinated by long tongued large bees. Some medium-sized and small pollen-foraging bees were occasional legitimate visitors,...

Multi-strata agroforesty systems for conservation of tree species genetic resources. Repositório Alice
SOUSA, N. R..
It is discussed the growth of five forest species, testing the viability model for in field conservation that put together agroforestry production principles with genetic and ecological stability of natural populations of autochthonous plant species. The preliminary results bring out a possibility for tansferring the model through a participatory approach to family farmers, institution with landscape projects, communities assisted by by non-governamental organizations. In the model species used for production should be chosen by the model users, whereas the species used for conservation should be the ones indicated from research (pau-rosa, mahogany, or virola).
