“…O uso de plantas medicinais na cura e tratamento de enfermidades é tão antigo quanto a espécie humana e, atualmente, sua utilização encontra-se em expansão por todo o mundo, representando um importante recurso natural e terapêutico para muitas comunidades e grupos étnicos (SARAIVA et al, 2015;SADAT-HOSSEINI et al, 2017).…”

“…For example, peak 6 had maximum detection on September (EAFE1); while peaks 8, 12 and 15 apparently were more found in April and January (Figure 1). Regarding the qualitative results for leaf extracts, EALE2 showed the highest number of peaks (8). Only two peaks were specific for EALE2 (12 and 13) and peak 14 was only absent for EALE1; the other peaks were present in all extracts.…”

“…[4][5][6][7] In recent years, the ethnomedicinal knowledge has stimulated several studies about the pharmaceutical potential of natural products of northeastern Brazil. 8 This is justified by the fact that the intrinsic features of Caatinga area (drought, high solar radiation rates and other environmental stresses) influence the synthesis of secondary metabolites of its plants, 9 making them attractive targets for bioprospecting programs. 10 In traditional medicine, Anadenanthera colubrina (Vell.)…”

Background: Anadenanthera colubrina (Vell.) Brenan var. cebil (Griseb) is a plant widely used for medicinal proposes in Brazilian Northeast. Objective: This study aimed to analyze the influence of rainfall indexes (RI) in antimicrobial activity and phytochemical constituents of extracts from leaves and fruits of A. colubrina. Material and Methods: Samples were collected in Catimbau National Park (Buíque, Pernambuco, Brazil) at September 2010 (RI: 75 mm) and January (RI: 65 mm), April (RI: 162 mm) and June 2011 (RI: 73 mm). The extracts were prepared by Soxhlet extraction using cyclohexane, chloroform, ethyl acetate and methanol. The antimicrobial activity was determined by MIC and MBC values. Results: All extracts showed antimicrobial activity, but ethyl acetate extracts (from all periods) were more active. Strong correlations were found between the RI and the average MIC of MLE (ρ: -0.99), EALE (ρ: -0.81), CHFE (ρ: -0.81), EAFE (ρ: -0.80); while moderate and weak correlations were found for other extracts. Through a HPLC analysis was possible to reveal that the samples collected from dry periods had more chemical diversity (as they presented more peaks). Gallic acid and quercetin (and derivative compounds) were identified. The levels of quercetin were enhanced in extracts from dry months. Conclusion: Our results showed that the rainfall has a positive effect on the antimicrobial activity of leaves and fruits of A. colubrina, however these extracts showed more chemical diversity during dry months.

“…It is widely used in reforesting projects in northeastern Brazil because it is a pioneer species that is capable of nitrogen fixation and drought resistance (Lorenzi, 2008). The species has significant economic value due to medicinal properties (Oliveira et al, 2012;Saraiva et al, 2015). However, it is rare in some regions of Brazil due to intense exploitation and suppression of natural occurrence areas.…”

ABSTRACT. Erythrina velutina Willd. (Fabaceae: Papillionoideae) is a pioneer species found in tropical and subtropical regions of the world that has medicinal properties and that is used in reforestation projects. This species is rare in some areas of northeastern Brazil. This study aimed to characterize and compare genetic structures of natural and restored populations of E. velutina, with a focus on the selection of tree seeds. A total of 108 individuals from five natural populations and one restored population were analyzed using ISSR markers, resulting in 407 polymorphic fragments. A high rate of polymorphism was observed in the restored population. The highest genetic variability was identified within populations (82%). Genetic bottleneck tests were significant for the Carmópolis/Rosário do Catete and Laranjeiras natural populations along with the Laranjeiras restored population. Genetic distances significantly correlated with spatial distance. Only the restored population retained unique alleles. Similarly, increased genetic distance was observed in individuals of the restored populations compared to the other populations. Observed genetic variation in both natural and restored populations of E. velutina was moderate, thus enabling selection of divergent trees from those trees supplying seeds. Environmental protection and management of these areas is necessary for the maintenance of these individuals and subsequent reproduction. We recommend suggestions for E. velutina conservation, since the restoration model adopted in this study did not promote the development of the specimens until the reproductive stage in a fashion that aims to augment the soil seed bank supply, as is suggested for pioneer species.
