The leaves of Echinodorus grandifl orus are used traditionally in Brazil for their diuretic and antirheumatic activities. In order to obtain more information about its phenolic constituents, an ethanol leaf extract was fractionated. Five glucosylfl avones, fi ve hydroxycinnamoyltartaric acids and trans-aconitic acid were isolated and their structures identifi ed by NMR data and chiral HPLC. Quantitative determination of compounds 1 11 by HPLC indicated caffeoylferuloyltartaric acid with 0.13… CONTINUE READING
