“…Most of the reductions in morphological traits caused by the drought showed low levels of plasticity (Figure 3). This response may reflect the ecological characteristics of tree species with a slow growth rate, such as B. cheilantha (Vaccaro et al, 1999;Vaz & Tozzi, 2003), which tend to express greater stabilization of their growth rates even in heterogeneous environments. This phenomenon was also noted in seedlings of Hymenaea coubaril L., a species from the same botanical family and similar ecology.…”

Drought-induced alterations often result in plant acclimation responses, though the extent to which these traits adjust, and their true significance remain species-specific and subject to debate. In order to discern which traits exhibit plasticity and essentiality for the species' survival, we studied the morpho-physiological responses of Bauhinia cheilantha seedlings subjected to varying water regimes. We examined modifications in growth patterns, resource allocation and partitioning, morphological traits, organic solute synthesis, relative water content in leaves and roots, and the plasticity index for each trait under different water supply levels. Several traits linked to plant growth were reduced under stress, but those changes were not considered to be plastic. The concentration of organic solutes increased under stress and exhibited a reversible behavior by reducing their levels after re-irrigation. These alterations underscored the significance of such compounds for survival during water deficit periods and the high degree of adaptability. B. cheilantha exhibits morpho-physiological plasticity, as demonstrated by alternating high levels of plasticity in physiological and morphological features, which are associated with moderate drought stress. The study discusses how these changes affect the growth and survival of the species.

“…Bauhinia ungulata L. var. obtusifolia (Ducke) Vaz, vernacular “pata-de-vaca,” is a tree from the Leguminosae family, considered to be endemic to Brazil, of which occurrence has been confirmed in the Brazilian North Amazonia and Northeast regions [ 1 , 2 , 3 ]. The leaves, like those of other species of the genus, are empirically used as an infusion to treat diabetes [ 4 , 5 ].…”

Species belonging to the Bauhinia genus, usually known as “pata-de-vaca”, are popularly used to treat diabetes. Bauhinia ungulata var. obtusifolia (Ducke) Vaz is among them, of which the leaves are used as a tea for medicinal purposes in the Amazon region. A microencapsulation study of lyophilized aqueous extract from Bauhinia ungulata leaves, which contain phenolic compounds, using five different wall materials (maltodextrin DE 4-7, maltodextrin DE 11-14; β-cyclodextrin; pectin and sodium carboxymethylcellulose) is described in this paper. The microstructure, particle size distribution, thermal behavior, yield, and encapsulation efficiency were investigated and compared using different techniques. Using high-performance liquid chromatography, phenolics, and flavonoids were detected and quantified in the microparticles. The microparticles obtained with a yield and phenolics encapsulation efficiency ranging within 60–83% and 35–57%, respectively, showed a particle size distribution between 1.15 and 5.54 µm, spherical morphology, and a wrinkled surface. Among them, those prepared with sodium carboxymethylcellulose or pectin proved to be the most thermally stable. They had the highest flavonoid content (23.07 and 21.73 mg RUTE/g Extract) and total antioxidant activity by both the DPPH (376.55 and 367.86 µM TEq/g Extract) and ABTS (1085.72 and 1062.32 µM TEq/g Extract) assays. The chromatographic analyses allowed for quantification of the following substances retained by the microparticles, chlorogenic acid (1.74–1.98 mg/g Extract), p-coumaric acid (0.06–0.08 mg/g Extract), rutin (11.2–12.9 mg/g Extract), and isoquercitrin (0.49–0.53 mg/g Extract), compounds which considered to responsible for the antidiabetic property attributed to the species.

“…To address these issues, we determined the effects of abiotic factors on both metabolisms of native Brazilian species. Bauhinia ungulata was selected for use in this study, owing to its medicinal use and wide distribution in the Southeast Cerrado [ 2 , 16 ]. The Cerrado climate is characterized by two predominant and well-marked seasons: a rainy period with the highest temperatures, and the dry season, with mild temperatures [ 17 ].…”

NMR-Based Metabolomics Reveals Effects of Water Stress in the Primary and Specialized Metabolisms of Bauhinia ungulata L. (Fabaceae)

et al. 2023

Bauhinia ungulata is a plant used in Brazilian traditional medicine for the treatment of diabetes. Phytochemical studies revealed flavonoids and the saccharide pinitol related to hypoglycemic activity of the Bauhinia species. To determine the effects of water deficit on ecophysiological parameter and metabolite fingerprints of B. ungulata, specimens were treated with the following water regimens under greenhouse conditions: daily watering (control), watering every 7 days (group 7D), and watering every 15 days (group 15D). Metabolite profiling of the plants subjected to water deficit was determined by LC-HRMS/MS. An NMR-based metabolomics approach applied to analyze the extracts revealed increased levels of known osmoprotective and bioactive compounds, such as D-pinitol, in the water deficit groups. Physiological parameters were determined by gas exchange in planta analysis. The results demonstrated a significant decrease in gas exchange under severe drought stress, while biomass production was not significantly different between the control and group 7D under moderate stress. Altogether, the results revealed that primary and specialized/secondary metabolism is affected by long periods of severe water scarcity downregulating the biosynthesis of bioactive metabolites such as pinitol, and the flavonoids quercetin and kaempferol. These results may be useful for guiding agricultural production and standardizing medicinal herb materials of this medicinal plant.
