Constituintes fenólicos e terpenóides isolados das raízes de Andira fraxinifolia (Fabaceae)

Abstract: Recebido em 2/8/05; aceito em 17/2/06; publicado na web em 6/7/06 PHENOLIC CONSTITUENTS AND TERPENOIDS ISOLATED FROM THE ROOTS OF Andira fraxinifolia (FABACEAE). Sitosterol, stigmasterol, betulinic acid, lupeol, 3-O-β-D-glucopiranosylsitosterol, 3-O-α-L-rhamnopiranosylchromone, 5,7-dihydroxy-4'-methoxyisoflavone, 3',5,7-trihydroxy-4'-methoxyisoflavone and a mixture of two rel-2R,3S-3-O-α-L-rhamnopiranosilflavanonols were isolated from the roots of Andira fraxinifolia. Their structures were established by spect… Show more

“…[1] In Brazil, the genus is represented by 27 species and 7 varieties being the majority native to the Amazon forest. [1,2] In traditional medicine, plants of this genus are used as purgative, febrifuge, narcotic, insecticide, piscicide, and antimalarial. [3 -6] Nevertheless, the genus is known as a putative natural anthelmintic agent.…”

“…[3 -6] Nevertheless, the genus is known as a putative natural anthelmintic agent. [1,2,5] Previous phytochemical investigations have shown that Andira species are a rich source of phenol compounds including pterocarpans, arylbenzofurans, flavanonols, rotenoids, and isoflavones. [2 -9] Owing to the occurrence of isoflavones in all Andira species previously investigated, these secondary metabolites seem to be of chemotaxonomic significance.…”

“…In this paper we describe the first iodination reaction of two flavonoids (Fig. 1), the flavonol quercetin 3,7,3 , 4 -tetramethyl ether (1, 3,7,3 , 4 -tetra-O-methylquercetin, retusin) isolated from Solanum species (Silva 2002, Silva et al 2004) and the isoflavone 7,4 -di-Omethylgenistein (2, 5-hydroxy-4 , 7-dimethoxyisoflavone) obtained by selective methylation of bichanin A (5,7-dihydroxy-4 -methoxyisoflavone) isolated from Andira species (Silva et al 2006(Silva et al , 2007, using iodine as an inexpensive and easily available reagent. These flavonoids have C-6 or C-8 positions as two sites for electrophylic substitutions.…”
