Abstract Background Dipteryx alata Vogel popularly known as "baru" is an important commercial leguminous tree species from the Brazilian Cerrado, which possess medicinal properties, besides its fruits consumption by animals and humans. The use of the "naturally occurring plants" as herbal remedies and foods mainly from leaves, seeds, flowers and roots of plants or extracts require precautions before ensuring these are safe and efficacious. The objective of this study was to evaluate the safety of D. Methods Vegetal drugs of D. All in vivo parameters reproductive ability evaluation, physical development of rat offsprings, and neurobehavioral development assays showed no changes related to control group.

Metrics details Abstract The expansion of land use for agricultural interests and the excessive use of herbicides are among the causes of biodiversity losses in the Brazilian Cerrado biome. Therefore, we aimed to test the hypothesis that Dipteryx alata Vogel, a common species in this biome, is sensitive to nicosulfuron because of its high phytotoxicity.
We evaluated physiological, biochemical and morphological responses in D. Young plants were transplanted to 10 L pots containing substrate composed of soil and sand after fertilization. After an acclimation period, the following doses of nicosulfuron were applied: 0 control , 6, 12, 24, 48, and 60 g a.
The experiment was conducted in a randomized block design factorial scheme with six doses of nicosulfuron, three evaluation times, and five replicates per treatment. The effects of the herbicide were assessed by measuring gas exchange, chlorophyll a fluorescence, photosynthetic pigments, membrane permeability, antioxidant enzymes and acetolactate synthase.
Nicosulfuron altered the photosynthetic machinery and enzymatic metabolism of D. Reductions in physiological traits, increased catalase and ascorbate peroxidase activities, enhanced malondialdehyde concentrations rate of electrolyte leakage and decreased acetolactate synthase activity in response to nicosulfuron all suggest that D.
