Sociedade Brasileira de Química, v. 31, n. 4, p. 802-806, 2008.0100-4042http://hdl.handle.net/11449/26377The phytochemical investigation of the flowers of Pterogyne nitens (Caesalpinioideae) resulted in the isolation and identification of nine phenolic derivatives, quercetin 3-O-sophoroside, taxifolin, astilbin, ourateacatechin, caffeic, ferulic, sinapic, chlorogenic and gallic acid, besides two guanidine alkaloids, pterogynine, pterogynidine. This is the first time these compounds have been reported in P. nitens flowers. As this is a monospecific genus, these secondary metabolites may have taxonomical significance. Their structures were assigned on the basis of spectroscopic analyses, including two-dimensional NMR techniques.802-806porPterogyne nitensflavonoidsguanidine alkaloidsArtigo10.1590/S0100-40422008000400018S0100-40422008000400018WOS:000256956200018Acesso abertoS0100-40422008000400018.pdf47020049042312481308042794786872448408368525167309927364527645500000-0002-1516-7765
