Chemical Constituents from Roots of Flemingia philippinensis

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.
