Saponins, tannins and flavonols found in hydroethanolic extract from Periandra dulcis roots

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 spe...
