The neotropical genus Swartzia Schreb. (Fabaceae) is an abundant and well distributed taxon. This work aimed to review the chemical and biological data published about Swartzia spp. For this purpose, there were screened 199 papers which were found related to keyword “Swartzia” in the scientific database ‘SciFinder’ and also checked up to 9,180 results returned from that same term in ‘Google Scholar’. There were obtained chemical and biological information related to 21 species. Chemical screenings performed with Swartzia species allowed to find mostly the chemical classes of: flavonoids, isoflavanones, isoflavones, pterocarpans, triterpenoids, diterpenoids, steroids and saponins. Isolated compounds and extracts were tested for several biological activities showed to be antifungal, antibacterial, larvicidal and antioxidant.

“…5 Por outro lado, a isoflavona 3 está sendo relatada pela primeira vez no gênero Vatairea. O isolamento das antraquinonas 1 e 2 é um fato importante, pois como esta classe de substância ocorre comumente em espécies do gênero Vatairea, 25 pode ser considerada como um marcador químico do gênero.…”

The chemical study of ethanol extract of sapwood of Vatairea guianensis Aubl. resulted in the isolation and structural identification of two compounds not previously described in the literature for the species, namely bolusanthol D and formononetin. In addition, other common compounds were identified, such as physcion, chrysophanol, betulinic acid, sitosterol and stigmasterol. The structural elucidation of substances was performed by spectroscopic data of 1 H and 13 C NMR and bidimensional techniques and comparison with the literature data. The ethanol extract of sapwood showed a significant antioxidant activity (EC 50 = 3.7 ± 0.3 µg mL-1) by DPPH radical scavenging method in comparison to Trolox (EC 50 = 4.5 ± 0.1 µg mL-1). This work is the first describing on chemical studies and antioxidant potential of the sapwood to V. guianensis.

RESUMO: "Constituintes químicos de Swartzia apetala Raddi var. glabra e avaliação da atividade antifúngica contra espécies de Candida". Do extrato hexânico da madeira de Swartzia apetala Raddi var. glabra foram isolados um estilbeno (1), uma flavanona (2), um pterocarpano (3), um triterpeno (4) e uma mistura de esteróides (5 a 7). O extrato bruto e as substâncias isoladas foram submetidas à avaliação do potencial antifúngico usando nove cepas padrão ATCC do gênero Candida. Entre as substâncias testadas apenas o triterpeno (4) e a mistura de esteróides (5 a 7) não apresentaram atividade. As estruturas das substâncias foram determinadas através da análise dos espectros de CG/EM, e RMN (1D e 2D) e comparação com dados da literatura.Unitermos: Swartzia apetala, atividade antifúngica, estilbeno, flavonoides, terpenóides. ABSTRACT:From the hexanic extract of the stem from Swartzia apetala Raddi var. glabra were isolated one stilbene (1), one flavanone (2), one pterocarpan (3), one triterpene (4) and a mixture of three steroids (5 to 7). The crude extract and the compounds isolated were submitted to evaluation of the antifungal activity against nine yeast standard ATCC of the Candida genus. Among the compounds only the triterpene (4) and the mixture of steroids (5 to 7) showed no activity. The structures of the compounds were determined by spectral data analysis of GC/MS and 1 H and 13 C NMR (1D and 2D experiments), as well as comparison with literature values.
