Abstract

This project intends to realize the chemistry study of leaves EtOAc fraction obtained from the leaves ethanolic crude extract of Vochysia divergens Pohl (Vochysiaceae), a native species from Pantanal Biome. This region has been selected for study within the Regular Research Project "Bioactive compounds from medicinal and food plants of the Cerrado and Pantanal and their endophytic microbiota (Fapesp Process # 2011/00631-5). The selected fraction showed activity in in vitro schistosomicidal assay carried out by our research group. Therefore, the the phytochemistry approach will be bioassay-guided on this activity. The proposed schistosomicidal test will be held evaluating the life cycle of Schistosoma mansoni vector. The analytical methodologies will employ chromatography techniques (CC and HPLC-DAD). The chemical structures of the isolated compounds will the assign on the bases of 1D and 2D NMR experiments. Thus, the main goal of this proposal will be identify the potential schistossomicidal of natural compounds, as well as contribute to the human resource formation in the natural product area in Brazil.
