“…The aerial parts of H. velutina were collected in February 2015 in Serra Branca/Raso da Catarina (Jeremoabo City, Bahia, 09°53′15.5′′; 09°44′34.6′′ S and 38°49′36,1′′; 38°52′20.4′′ W) [ 38 ]. The material was identified by Prof. Adilva de Souza Conceição (UNEB) and a specimen voucher (28709-1) was kept in the Herbarium of the State University of Bahia (HUNEB, Paulo Afonso Collection).…”

New Sulphated Flavonoids and Larvicidal Activity of Helicteres velutina K. Schum (Sterculiaceae)

et al. 2018

Helicteres velutina K. Schum (Sterculiaceae), commonly known in Brazil as ‘pitó’, is traditionally used by indigenous peoples as insecticides and repellents. The present work reports on the the phytoconstituents from aerial parts of H. velutina and evaluation of the larvicidal potential of its extract. The compounds were isolated using chromatographic techniques and identified by NMR, IR and LC-HRMS. This study led to the isolation of a fatty acid, one aliphatic alcohol, four chlorophyll derivatives, one steroid, triterpenes, a lignan, and flavonoids, highlighting the new compounds in the literature, 5,4′-di-hydroxy-7-methoxy-8-O-sulphate flavone (mariahine) (15a) and 5,3′-di-hydroxy-7,4′-dimethoxy-8-O-sulphate flavone (condadine) (15b). The work presented here contributes to the chemotaxonomic knowledge of the Sterculiaceae family by describing the occurrence of sulphated flavonoids in this family for the first time. The crude ethanolic extract of H. velutina featured robust larvicidal activity against Aedes aegypti larvae, showing that the extract can be useful as a domestic larvicide, just as indicated by traditional use, to combat A. aegypti, a vector insect of severe viral diseases, such as dengue and Zika.

“…The secondary veins ranged from broquidodromous to eucamptodromous, although this first type is a common standard for Rubiaceae (Mattos 2011, Mantovani et al 1995, Da Cunha & Vieira 1997, the latter was well represented in this study, constituting 50% of the species studied, Varjão et al (2013) observed the same parameters. The species Borreria spinosa, Cordiera rigida, Hexasepalum teres e Mitracarpus salzmannianus showed a variation between these two types, described as eucamptodromous-brochidodromous, where secondary veins are strongly curved, joining lightly to each other.…”

Leaf architecture of Rubiaceae Juss. from caatinga vegetation in Brazil

et al. 2018

The study and characterization of leaf venation plays a key role in the recognition of taxonomic groups that have been identified mainly based on reproductive traits. This study aimed at characterizing the pattern of leaf venation of Rubiaceae, recognizing individual characters among the taxa of this group and testing the use of leaf architecture as a taxonomic tool capable of providing vegetative and diagnostically characteristics between species. Leaves of 14 species distributed in eight genera from Rubiaceae were diaphanized and classified. The study area is located in Área de Proteção Ambiental Serra Branca/Raso da Catarina, Bahia State, Brazil. The characterization of secondary veins, including type, spacing and number of pairs, third veining patterns, fourth and fifth order, and the conformation of the areola were useful to delimit taxa when used together, providing subsidies to more comprehensive studies.

Leguminosae includes six subfamilies, where the traditionally recognised subfamily Mimosoideae was accepted as a distinct clade included within the recircumscribed subfamily Caesalpinioideae, called informally as Mimosoid clade. The representatives of the tribes Acacieae and Ingeae can be differentiated principally in terms of the patterns of their stamens, being free in Acacieae and monadelphous in Ingeae. The floristic survey of Acacieae and Ingeae in the Environmental Protection Area Serra Branca included analysis of specimens collected from June 2011 to September 2012. The analyses were supplemented with dried collections from the following herbaria: ALCB, HRB and HUEFS. Ten species were cataloged, distributed among four genera of Ingeae: Calliandra Benth. (1 sp.), Chloroleucon (Benth.) Britton & Rose ex Record (1 sp.), Enterolobium Mart. (1 sp.), Pithecellobium Mart. (1 sp.); and one genus of Acacieae: Senegalia Raf. (6 spp.). The most representative species were Calliandra aeschynomenoides Benth. associated with sandy and stony soils and Chloroleucon foliolosum (Benth.) G.P.Lewis and Senegalia bahiensis (Benth.) Seigler & Ebinger growing on sandy-clay soils. The taxonomic treatment includes a key for the identification, descriptions, illustrations, photos, data of the geographical distribution phenological data and comments about the species.
