“…However, S. campanulata, M. acuminata and N. laevis are morphologically well characterized and can be distinguished by their spathaceous calyx splitted on adaxial (S. campanulata, M. acuminata) or abaxial side (N. laevis), respectively. Furthermore, the latter two members can be differentiated by their ovules and fruits (Hutchinson and Dalziel, 1963;Steentoft, 1988). These aspects have obviously been ignored in the past.…”

“…(Schoonhoven et al, 1998), with long chain hydrocarbons and derivatives thereof as principle constituents (Baker, 1982). Terpenoids and flavonoids also occur, the latter being reported for cuticular waxes of some species and used as taxonomic features (Stermitz et al, 1992;Wollenweber et al, 1996;Blatt et al, 1998;Alcerito et al, 2002). This paper deals with compositional studies of the cuticular waxes of N.…”

The cuticular waxes, obtained by chloroform extraction from the leaves of four African Bignoniaceae, Newbouldia laevis, Markhamia acuminata, Spathodea campanulata and Kigelia africana were analysed by GC-MS. The principal constituents were represented by a homologous series of n-alkanes (C 23 ÐC 33 ), n-alcohols (C 18 ÐC 30 ) and related carboxylic acids (C 16 Ð C 36 ). For N. laevis and M. acuminata, ursolic and oleanolic acid were the most abundant wax components (52 and 60%, respectively), followed by the C 29 , the C 31 and the C 33 n-alkanes. The predominant components of S. campanulata were n-alcohols (35%), with octacosanol and triacontanol as the most abundant ones, while K. africana is distinguished from these three members by the conspicuous absence of triterpenoic acids and the predominance of n-alkanes (70%) with hentriacontane and tritriacontane as the main representatives. Other notable constituents were sterols, albeit present in trace amounts. The wax profiles are discussed in terms of taxonomic characters.

“…Aplicações locais são feitas através de compressas ou banhos (Maia et al, 1994;Costa et al, 1990) e até em cosméticos (Biavatti et al, 2007). Dessa espécie já foram isolados taninos, 7,4-dihidroxi-5-metoxiflavona, fitosteróis, flavonóides, pigmentos utilizados em cosméticos como: carajurona e carajurina, compostos derivados das 3-deoxiantocianidinas como a antocianidina, o pigmento 1, o pigmento 2 e a luteolina e flavona carajuruflavona também foi isolada de Arrabidaea chica (Takemura et al, 1995;Zorn, 2001;Alcerito et al, 2002;Devia et al 2002). Testes de toxicidade aguda indicaram que a DL50 em camundongos, ultrapassa 2 g/kg i.p.…”

RESUMO:O estudo investigou o efeito antiinflamatório do extrato aquoso da Arrabidaea chica (Humb. & Bonpl.) B. Verl., Bignoniaceae, popularmente conhecida como "crajiru", sobre o edema induzido por venenos de serpentes amazônicas dos gêneros Brothrops e Crotalus, em camundongos albinos, por via oral, intraperitoneal e subcutânea. O efeito anti-edematogênico foi avaliado pela medição do diâmetro dos coxins das patas posteriores, sendo medidos as 1, 3, 6, 12 e 24 horas, para B. atrox e 1, 3 e 6 horas para Crotalus durissus ruruima, e também avaliado por histopatologia. O estudo mostrou que o efeito inibitório do extrato aquoso para o gênero Bothrops, pelas vias subcutânea e intraperitoneal (12 horas) foi de 55,87% e 65,70%, respectivamente. Para o gênero Crotalus o efeito inibitório do extrato pela via subcutânea após 3 horas foi de 33,55% e após 6 horas de 79,81%. Pela via intraperitoneal após 3 horas foi de 48,02% e após 6 horas de 92,52%. Na análise histopatológica, o infiltrado de granulócitos e a miocitólise foram os efeitos inflamatórios inibidos mais significativamente. Os resultados sugerem a presença no extrato aquoso de A. chica de substâncias com atividade inibitória sobre os efeitos inflamatórios dos venenos das serpentes Bothrops atrox e Crotalus durissus ruruima.Unitermos: Arrabidaea chica, Bignoniaceae, plantas medicinais, venenos, serpentes, atividade antiinflamatória.ABSTRACT: "Anti-inflammatory activity of the aqueous extract of Arrabidaea chica (Humb. & Bonpl.) B. Verl. on the self-induced inflammatory process from venoms amazonians snakes". The study investigated the anti-inflammatory effects of the aqueous extract (EAq), the Arrabidaea chica (Humb. & Bonpl.) B. Verl., Bignoniaceae, known as the "crajiru", tested on the paw oedema induced in inflammatory process by venoms Amazon snakes from the Bothrops and Crotalus species, on albino mice. This process was done by an oral, intraperitoneal and subcutaneous way. The cushions thickness was measured at time breaks of 1, 3, 6, 12 and 24 hours, Bothrops genus and 1, 3 and 6 hours, Crotalus genus, and a histopathologic analysis was made. The Bothrops genus, was used as an inhibitory effect for the subcutaneous and intraperitoneal way (12 hours), and it had an inhibition of 55.87% and 65.70%, respectively. For the Crotalus genus, the inhibitory effect for the subcutaneous way after 3 hours was the 33.55% and 79.81%, after 6 hours. The intraperitoneal way affect after 3 hours had an inhibition of 48.02% and 92.52% after 6 hours. For the histopathological analysis, the leucocytes infiltration and the miocitolisis were the most expressive parameters and thus inhibited. The results suggest the presence of active principles with anti-inflammatory effects.
