The growing commercial demand for products with medicinal use has caused overexploitation of several plant species worldwide. To prevent the decline of these populations, the collection of these resources should be done in a sustainable way considering the time of its replacement in natural stocks. This study was designed to identify the relationship between different intensities of extraction of bark from the trunk of Stryphnodendron rotundifolium Mart. and its regeneration speed. For this, we selected two areas of Cerrado in the Northeast of Brazil, where a monitoring experiment with duration of 24 months was performed. This experiment consisted in simulating different extractive damage to assess the regeneration of bark. In each area, we selected 20 individuals, among which four treatments with five repetitions were implemented. The data showed that in both study areas, the trees regenerated their shells faster when subjected to higher collection intensities. However, this regeneration was not related to variations in rainfall in the environment.

The study aimed to evaluate the inclusion effects of Stryphnodendron rotundifolium (barbatimão) extracts in substitution of the lasalocid sodium on the ingestive behaviour, intake, ruminal parameters, and digestibility of feedlot lambs. Twenty-four pantaneiro lambs were used, with an average age of 150 ± 4.59 days and an initial body weight of 21.

This study investigated the flavonoid content, antioxidant activity, and toxicological properties of the acetone-water fraction of stem bark of Mart. (TFSR). The total flavonoid content and antioxidant activity were determined, as typified by DPPH and ABTS radical scavenging abilities, Fe reducing antioxidant power (FRAP), relative antioxidant capacity (RAC), and the inhibition of thiobarbituric acid reactive species (TBARs) in tissue.

Mart., popularly known as "barbatimão", is a plant species traditionally used by topical and oral routes for the treatment of infectious and inflammatory diseases. Considering the well-described antioxidant properties of this species, this study investigated the protective effects of its keto-aqueous extract using an in vitro model of iron overload.

In this study, we report the development and characterization of 15 new microsatellite markers for (Leguminosae) in order to support future analyses of genetic diversity in populations of this species. In screening with 48 individuals from three different populations of , we tested the amplification of 20 microsatellite loci, of which five are not useful for population genetic studies due to the lack of polymorphisms or amplification failures. For the final set of 15 loci, the number of alleles ranged from 2 to 15, with a total of 116 alleles.
