“…High density of T. fagifolia was detected in the area, which may be associated with the morphology of its fruit characterized as winged, allowing anemochory dispersion, as well as by its irregular spatial distribution (Ribeiro et al, 2018;Soares Neto et al, 2014). This species is commonly found in the Cerrado, with its occurrence in the Brazil southeast region being only in Minas Gerais state.…”

The Cerrado domain is considered as one of the global hotspots, although studies upon management in this vegetation type have many gaps in the forest literature. Thus, it’s important to propose viable alternatives to its use. This study aimed to evaluate the technical feasibility of forest management in a legal reserve of cerrado sensu stricto in Minas Gerais state, as support to the local increased demand for firewood. A forest inventory was applied from systematic samplings of 10 plots, based on the diameter criteria at 0.30 m above ground (DAG) ≥ than 5 cm. The Shannon diversity index (H') and Pielou's equability (J) were used. Furthermore, diametric distribution models and the diameter classes were evaluated by De Liocourt quotient. We observed that the Shannon diversity was 2.61 nats.ind-¹ and the Pielou (J) equability was 0.74. The De Liocourt quotient showed a non-constant mean value of 1.97 between the diameter classes. None of the fitted models showed results likewise the frequency observed in the study. The total wood volume estimated was 2,189.6765 m³. The study area possibly suffered anthropic interventions, resulting both low volumetric yield and species diversity. Thus, the forest management to the legal reserve area was considered unfeasible, as it does not present technical sustainability.

“…It is distributed from Mexico to Bolivia, according to Stace (2010). In Brazil, it has been confirmed in the Northern and Northeastern regions, in the states of Maranhão, Pernambuco and Piauí (BFG 2018;Ribeiro et al 2018b;Ribeiro et al 2020), occurring only in Ombrophilous Forest vegetation. The species was found in the area of the Ka'apor Indigenous Reserve, a region of preserved forest.…”

We present the floristic treatment of the Terminalia species occurring in the state of Maranhão. This study was based on the analysis of national and international herbaria. Six species were recorded from the state: Terminalia actinophylla, T. amazonia, T. dichotoma, T. fagifolia, T. glabrescens, and T. lucida, with one endemic (T. actinophylla) to Brazil. Taxa were commonly recorded in dry Savanna environments (cerrado). Only the species Terminalia fagifolia and T. lucida occur in conservation units in Maranhão, specifically in Mirador State Park, Chapada das Mesas National Park and Ecological Sanctuary of Pedra Caída. In addition to morphological descriptions, this study includes an identification key, illustrations, and comments about taxonomic affinities, geographical distribution, ecology, conservation status, and phenology of the species.

“…Terminalia catappa is a plant species belonging to the Combretaceae family, commonly known as "amendoeira" or "castanhola" [8,9]. In Brazil, it is found mainly in the Northeast region of the country [10]. Its leaves have biologically active compounds with some activities described in the literature, including anti-inflammatory and immunomodulatory [11], antidiabetic [12], antibacterial [13] and anticancer [14,15].…”

Chagas disease is a severe infectious and parasitic disease caused by the protozoan Trypanosoma cruzi and considered a public health problem. Chemotherapeutics are still the main means of control and treatment of the disease, however with some limitations. As an alternative treatment, plants have been pointed out due to their proven pharmacological properties. Many studies carried out with Terminalia catappa have shown several biological activities, but its effect against T. cruzi is still unknown. The objective of this work is to evaluate the therapeutic potential of extracts and fractions obtained from T. catappa on the parasite T. cruzi, in addition to analyzing its antioxidant activity. T. catappa ethyl acetate fraction were produced and submitted the chemical characterization by Liquid Chromatography Coupled to Mass Spectrometry (LC-MS). From all T. catappa extracts and fractions evaluated, the ethyl acetate and the aqueous fraction displayed the best antioxidant activity by the 2,2-diphenyl-1-picryl-hydrazyl (DPPH) radical scavenging method (IC50 of 7.77 ± 1.61 and 5.26 ± 1.26 µg/mL respectively), and by ferric ion reducing (FRAP) method (687.61 ± 0.26 and 1009.32 ± 0.13 µM of Trolox equivalent/mg extract, respectively). The ethyl acetate fraction showed remarkable T. cruzi inhibitory activity with IC50 of 8.86 ± 1.13, 24.91 ± 1.15 and 85.01 ± 1.21 µg/mL against epimastigotes, trypomastigotes and intracellular amastigotes, respectively, and showed no cytotoxicity for Vero cells (CC50 > 1000 µg/mL). The treatment of epimastigotes with the ethyl acetate fraction led to drastic ultrastructural changes such as the loss of cytoplasm organelles, cell disorganization, nucleus damage and the loss of integrity of the parasite. This effect could be due to secondary compounds present in this extract, such as luteolin, kaempferol, quercetin, ellagic acid and derivatives. The ethyl acetate fraction obtained from T. catappa leaves can be an effective alternative in the treatment and control of Chagas disease, and material for further investigations.
