ObjectiveTo study the chemical constituents from the roots of Flemingia philippinensis.MethodsThe chemical constituents were isolated and purified by combination of silica gel column,Sephadex LH-20,polyamide,and ODS column chromatography.The structures of the isolated compounds were identified by means of spectral data.ResultsTen compounds were isolated from F.philippinensis and identified as isoderrone (1),dalparvin A (2),prunetin (3),7,3'-dihydroxy-5,4',5'-trimethoxyisoflavone (4),pratensein-7-O-β-D-glucoside (5),sissotrin (6),sophororicoside (7),formononetin (8),orobol (9),and biochanin A (10).ConclusionCompounds 1-6 are obtained from this plant for the first time.
