We investigated a strategy for the chemotaxonomy study of Chrysobalanus icaco Linnaeus (Chrysobalanaceae) based on ultra-high performance liquid chromatography coupled with diode array detection fingerprint in combination with multivariate analysis. Two models using principal component analysis and partial least squares discriminant analysis were developed, and the samples could be successfully classified into two classes: Class 1 (red morphotype) and Class 2 (white and black morphotypes). Furthermore, ultra-high performance liquid chromatography coupled with diode array and electrospray ionization tandem mass spectrometry was used to identify the main compounds responsible for class separation. The partial least squares discriminant analysis model accurately classified the C. icaco samples using an external validation subset with prediction ability of 100% and revealed the existence of two chemotypes. The most important finding obtained in this study is that the three morphotypes dis- tinguished by the mature fruit color (white, red, and black) are not all phytoequivalent to each other. |

The Pantanal is one of the world's largest wetland ecosystems, encompassing 140.000 km2. The region is a breeding ground for waterfowl, and enormous rookeries of storks, herons egrets, and ibises indicate a vast abundance of birds. the Pantanal is also one of the most important refuges for many of Brazil's threatened or endangered species, such as jaguars, giant anteaters, and swamp deer. The productive web of waters supports an important fishery undustry. The Pantanal, with its extraordinary diversity and abundance of wildlife, is a threatened region. Deforestation, expanding agriculture, illegal hunting and fishing, unplanned tourism, and pollution with pesticides have caused a progressive deterioration of the natural environment, placing one of Brasil'smost important ecosystems at risk. Gold mining is still common in the northern Pantanal. Along the Cuiaba river are 700 functional gold-mining dredges. In the town of Pocone, unregulated gold mines have also contaminated the area with mercyry, which is used during the processing of gold. Approximately 50% of the fishes from the Cuiaba River and 35% from the Bento Gomes River have mercury levels highter than 0.5 ug/g. which is beyond the international standard for contamination. Fishes from the Paraguay River have levels below 0.5. Birds like Phalacrocorax olivaceus, Aramus guarauna and Rosthramus sociabilis were also contaminated. No research has been conduted on the fate of pesticides in the Pantanal. However, because of the huge demand for soyabean...
