Luxenchalcone, a new bichalcone and other constituents from Luxemburgia octandra
Chromatographic fractionation of leaves and branches extracts from Luxemburgia octandra (Ochnaceae) afforded isoliquiritigenin, 3'-hydroxyisoliquiritigenin, b-sitosterol, stigmasterol, lupeol, betulinic acid, the biflavonoid, 4',5,7-trihydroxyflavone-(3'®O®4'")-5",7"-dihydroxyflavanone and a new bichalcone 4,2',4'-trihydroxychalcone-(3®O®4")-2'",4'"-dihydroxychalcone (luxenchalcone). The structures were established from analysis of IR, MS and NMR spectral data, including 2D-NMR experiments of the natural substances and of the luxenchalcone methyl derivative.
