“…For the subfamilies sampled, Faboideae presented the largest number of species (13spp), followed by Caesalpinoideae (10spp) and Mimosoideae (7spp), as shown in Figure 2. Faboideae is the largest subfamily of Fabaceae, features fairly wide distribution which confirms their representativeness in the tropical, subtropical areas, extending to temperate regions, but their greatest diversity is found in the tropics and African American (SILVA & TOZZI, 2012;SINISCALCHI, 2012). The most prevalent growth habit was tree (12 sp), followed by grass (8 sp), shrub (6 sp) and sub-shrub (4 sp), according to figure 3.…”

The research had the objective of identify the species of Leguminosae In the Buriti do Meio Environmental Protection Area, in the city of Caxias / Maranhao, Brazil, to describe the patterns of family diversity in relation to the subfamily, genus and species, as well as to determine the pattern of taxa distribution in the studied area. 26 genera were inventoried, distributed in 30 species. Faboideae presented the largest number of species, followed by Caesalpinoideae and Mimosoideae. The species showed habit of tree growth, followed by herb, shrub and sub-bush. It is hoped that the research has contributed to the conservation of the species and future studies of the taxa of this botanical family, which has importance as fodder, food, ornamental, medicinal, among others.

“…Furthermore, the fragment was mainly represented by Lonchocarpus nitidus, Myrcia palustris, Terminalia australis, Gymnanthes klotzschiana, Matayba elaegnoides, Pouteria salicifolia, Calyptranthes concinna and Campomanesia xanthocarpa, which showed the highest values of IVI and are characteristic species of riparian forests. The species with the second highest IVI was L. nitidus, a common species in riparian forests, which can be used for riparian forest recovery (Silva & Tozzi 2012). The occurrence of deciduous hygrophytes species, adapted to alluvial environments was also recorded, such as L. divaricata, Vitex megapotamica (Spreng.)…”

Phytosociological study of a riverine forest remnant from Taquari river, State of Rio Grande do Sul, Brazil). Aiming to characterize the structure of the arboreal community in a riverine forest remnant of the Taquari river, State of Rio Grande do Sul, 42 sampling units of 100 m 2 (10 × 10 m) were located. Phytosociological parameters were also assessed and the indexes of Shannon diversity (H') and Pielou evenness (J) were evaluated. A total of 39 species, 21 families, 2.83 nats ind -1 for H' and 0.77 for J were recorded. Among the species found, the endemic Callisthene inundata O.L. Bueno, A.D. Nilson & R.G. Magalh. and Picrasma crenata (Vell.) Engl. are included in the list of endangered species. The density found was of 1,557.14 ind ha -1 . Luehea divaricata Mart. and Lonchocarpus nitidus Benth. showed the highest indexes of importance values. Besides contributing to the knowledge of species distribution and community structure, this study points out the need for conservation of existing native forest remnants.

“…The specimen was confirmed as a species of L. cultratus by a systematic biologist, who took photographs of the vegetative and diagnostic characteristics of the specimen, in addition to collecting samples for the construction of the exsiccata. The analysis of the photographs followed the analytical key determined by Silva and Tozzi, 2012 [18], making it possible to identify the specimen as an L. cultratus. The voucher samples were deposited in the Herbarium of UNIOESTE (UNOP No.…”

Introduction: Trypanosoma cruzi is the agent of Chagas’ disease and affects approximately 6-8 million people worldwide. The search for new anti-T. cruzi drugs are relevant because only two drugs exist actually. The objective of this study was to investigate the effect of the extracts from the seeds of Lonchocarpus cultratus on T. cruzi, its cytotoxicity as well as to elucidate its chemical profile. Methodology: The characterization of the extracts was done using 1H-RMN. T. cruzi forms were treated with increasing concentrations of the extracts and after, the percentage of inhibition and IC50 or LC50 were calculated. Murine peritoneal macrophages were treated with different concentrations of the extracts to evaluate the cellular viability. The hemotoxicity was accessed by verifying the levels of hemolysis caused by the extracts on human red blood cells. Results: Chalcones isocordoin and lonchocarpin were detected in the dichloromethane extract, and chalcone lonchocarpin was detected in the hexane extract. The dichloromethane extract showed higher activity against all the forms of T. cruzi compared to the other two extracts, but the hexane showed the best selectivity index. The cytotoxicity observed in murine macrophages was confirmed in human erythrocytes, with dichloromethane extract having the highest toxicity. The methanolic extract showed the lowest anti-T. cruzi activity but was nontoxic to peritoneal murine macrophages and red blood cells. Conclusions: L. cultratus extracts have the potential to be explored for the development of new anti-trypanosomal drugs. This study was the first to demonstrate the action of extracts from the genus Lonchocarpus on infecting forms of T. cruzi.
