Resumo Periandra dulcis Mart. ex Benth. Fabaceae (Syn.: P. mediterranea (Vell.) Taub.) is native to the northern and middle parts of Brazil. In Brazilian ethnomedicine, their roots are used as anti inflammatory, expectorant, diuretic and laxative. An HPLC-ESI-MS/MS system was employed to provide a rapid method to make a tentative characterization of the compounds found in the hydroethanolic extract from P. dulcis roots. The structures of sixteen compounds found in this hydroethanolic extract were suggested mainly by MS data conjugated with the UVDAD spectra, reference compounds and available mass spectra data in literature. Saponin derivatives of hederagenin and soyasapogenol E, such as hederagenin-3-O-rhamnosyl glucosyl glucuronide, soyasapogenol E-3-O-rhamnosyl glucosyl glucuronide and periandrin isomers were found as the main constituents, with a minor content of flavonols quercetin and myricetin glycosides derivatives and hydrolysable tannins, such as dihexahydroxydiphenoyl galloyl glucoside and trisgalloyl hexahydroxydiphenoyl glucose.To the best of our knowledge, with exception of periandrins found in the roots, nothing has been published about the chemical composition of P. dulcis..
