... Popularly known as orchid tree due to the bilateral symmetry of its flowers, Bauhinia plants are also known in Latin American countries as 'pata de vaca' (cow's hoof) due to the bilobed leaves. The genus contains more than 300 plant species, 200 of which are reported in Brazil (Lorenzi, 2002;Vaz & Tozzi, 2005). Bauhinia forficata is the most common species of the genus in Brazil and is used in traditional medicine for the treatment of diabetes mellitus, dyslipidemias, general pain and inflammation (Cavalcanti & Favoretto, 2005;Cechinel Filho, 2009;Lorenzi, 2002;Menezes et al., 2007;Silva & Cechinel Filho, 2002). ...
Bauhinia forficata is an important plant commonly used in traditional medicine, and as an ornamental plant in parks and gardens. Its use as an ornamental plant is compromised by the symptoms of anthracnose. Although anthracnose caused by Colletotrichum species is a widespread plant disease and observed across several Brazilian regions, the species associated with this disease are unknown for most host species. The present study aimed to identify the Colletotrichum species associated with anthracnose of B. forficata in Brazil, as well as the prevalence and aggressiveness of each. Multilocus phylogenetic analyses including the loci APN2, APN2-MAT/IGS, CAL, GAP2/IGS, GAPDH, GS and TUB2 reveals that C. chrysophilum, C. siamense and C. tropicale are associated with B. forficata anthracnose across three different Brazilian geographic regions. Colletotrichum siamense was prevalent in all sampled regions and was also the most aggressive species on B. forficata leaves. The Colletotrichum species here reported have been found on several commercial crops. Since B. forficata commonly occurs as a native plant in areas near commercial fields, it may represent a potential source of inoculum to these crops.

Among the various geological formations found in the State of São Paulo, the Itaquaquecetuba Formation, located in the São Paulo sedimentary basin, is one of the richest in Cenozoic plant fossils, allowing a detailed study of the flora which existed in that region, from the Paleogene to the Early Neogene. The plants identified in this formation, in general, belong to the families Melastomataceae and Fabaceae of the angiosperms group. In this study, one foliar impression of Leandra (Melastomataceae), being this the first fossil record of the genus, and one of Bauhinia (Fabaceae) were identified. These foliar fragments allowed us to observe in detail the leaf architecture and then to carry out the generic assignment. The form assigned to the genus Leandra resembles more the current species L. acutiflora and that assigned to the genus Bauhinia suggests affinity with B. divaricata. However, the ancient registration and the lack of an accuracy of the diagnostic characteristics lead us to use Leandra sp. and Bauhinia aff. B. divaricata designations. Some aspects of the paleogeography of both genera are discussed.

Studies had indicate that excessive production of re-active oxygen species (ROS) affect cellular signaling pathways, which is associated with pathological and physiological conditions such as cancer, diabetes and neurodegenerative diseases In this context, our la-boratory has obtained the Bios-p, a ROS modulator, peptide analogue by sequencing from the seed of Bauhinia bauhinoides, which represents the active 12-amino acid, obtained from the inhibitor BbKI protease and we predicted the three-dimensional structure of Bios-p analogue peptide using homology modeling, being patented by the working group of Dr. Maria Luiza Vilela Oliva of UNIFESP, Brazil (a member of our cluster). The protective effect on the viability and antioxidant capacity of Bios-p was studied in HEK293T cells under oxidative stress in-duced by hydrogen peroxide (H2O2) using SYTOX-GREEN/DHE and luminescence assay. The three-dimensional structure of Bios-p peptide ana-logue was predicted by homology-based modeling using Modeller9v8. The pre-treatment with different concentrations of Bios-p (1-10 μM) showed a increase of 53.83+3.86% the cellular viability in under oxida-tive stress compared to control. Furthermore, the results to indicate that HEK293T cells by incubating for 24 h with Bios-p shown a significant decreased of basal extracellular ROS on total cell population in 89.67+0.76%, compared to control in the absence of the analogue. Similarly it is observed that Bios-p has a significant antioxidant effect on extracellular ROS production when cells are subjected to oxidative stress induced by 200 μM H2O2 in 64.37+4.63%, compared to control in absence of H2O2 and Bios-p. These results suggest that Bios-p has potential as antioxidant agent in cells HEK293T under H2O2-induced oxidative stress and that can protect the cells viability as concentration-dependent, and we propose a new biotechnological tool for modulate the ROS production.

Ethnopharmacological relevance:
Bauhinia platypetala Burch. is a traditionally used Brazilian medicinal plant, although no evidence in the literature substantiates the safety of its use.
Aim of the study:
The aim of this study was to investigate the safety of the ethanolic extract and the ethereal fraction of B. platypetala leaves.
Materials and methods:
The identification of chemical compounds from the B. platypetala ethanolic extract and its ethereal fraction was performed by GC/MS and ESI-MS/MS. The plant's toxicological, cytotoxic, mutagenic and genotoxic properties were determined in Saccharomyces cerevisiae strains and V79 cell culture by survival assays and comet assay.
Results:
The major compound identified in the B. platypetala ethanolic extract is palmitic acid, kaempferitirin and quercitrin, while the B. platypetala ethereal fraction was found to be rich in phytol, gamma-sitosterol and vitamin E. Moreover, the results indicated that the B. platypetala ethanolic extract has an anti-oxidative effect against H(2)O(2) in yeast. In addition, the B. platypetala ethanolic extract did not induce mutagenic effects on the S. cerevisiae N123 strain, but the ethereal fraction of B. platypetala at higher concentrations (250-500 μg/mL) induced cytotoxicity and mutagenicity. A slight cytotoxic effect was observed in mammalian V79 cells; however, both the B. platypetala ethanolic extract and its ethereal fraction were able to induce DNA strand breaks in V79 cells, as detected by the alkaline comet assay.
Conclusion:
The B. platypetala ethanolic extract has antioxidant action and showed absence of mutagenic effects in yeast S. cerevisiae. On the other hand B. platypetala ethereal fraction is mutagenic and does not show antioxidant activity in yeast. In mammalian cells B. platypetala ethanolic extract and it's ethereal fraction induce cyotoxic and genotoxic action.

A new lectin, BfL, was purified from Bauhinia forficata seeds by ammonium sulfate fractionation, DEAE-Sephadex ion exchange chromatography, Sepharose-4B and chitin affinity chromatographies and Superdex 75 size exclusion chromatography. The molecular homogeneity and purity of BfL were assessed by reversed-phase HPLC. BfL appeared as a single band of approximately 27.0 kDa on SDS-PAGE under non-reducing and reducing conditions, and its molecular weight was determined to be 27,850 Da by LC/ESI-MS. BfL is a glycoprotein with a carbohydrate content of 6.24% determined by the phenol–sulfuric acid method. Fetuin, asialofetuin, thyroglobulin and azocasein inhibited the hemagglutinating activity of BfL, whereas saccharides did not. BfL hemagglutinating activity was stable at 100 °C for 30 min, pH-dependent, with the highest activity at pH 6.0, and metal-independent. The primary structure of BfL shows similarity with other lectins from the genus Bauhinia. Deconvolution of the BfL circular dichroism (CD) spectrum indicated the presence of α-helix and β structures. BfL increases coagulation time, but this effect is not related to human plasma kallikrein or human factor Xa inhibition. BfL also inhibits ADP- and epinephrine-induced platelet aggregation in a dose-dependent manner and is the only currently described lectin from Bauhinia that exhibits anticoagulant and antiplatelet aggregating properties.

A study of pollen morphology, in species of the genera Bauhinia and Phanera (Leguminosae-Caesalpinioideae) which occur in the Brazilian caatinga, is presented. The pollen was examined using light and scanning electron microscopy. Samples were prepared by the KOH method; non-treated pollen grains were examined by scanning electron microscopy. Pollen grains in Bauhinia species (11) are colpate, but porate in B. cheilantha and B. subclavata. All four species of Phanera present colporate pollen grains; P. outimouta is the only to have syncolporate pollen grains. Species of both genera present heteromorphism in the number of apertures. Excepting P. outimouta whose pollen grains are psilate, all species in the two genera present supratectal processes (gemmae/clavae), however the exine in the two genera are different -semitectate, reticulate in Bauhinia species, and tectate, rugulate (or psilate) in Phanera ones. Pollen characters support the segregation of Phanera from Bauhinia.
