STUDIES ON FLAVONIOD CONSTITUENTS OF HEDYSARUM MULTIJUGUM

AIMTo study the chemical constituents from Hedysarum multijugum. METHODSThe compounds were separated by chromatography methods, their structures were identified by spectral analysis. RESULTS Six compounds were isolated and identified as β-sitosterol (1), 7-hydroxy-4′-methoxy isoflavone (2), betulic acid (3), 1,7-dihydroxy-3,9-dimethoxy pterocarpene (4), 5,7-dihydroxy-8-C-prenyl-4′-methoxy isoflavone (5) and 5,7-dihydroxy-4′-methoxy isoflavone (6). CONCLUSIONCompound 4 is a new compound and the others were obtained from the plant for the first time.
