[Objective]To study the chemical constituents of ethyl acetate fraction of ethanol extract from Moghania philippinensis(Merr.et Rolfe)Li roots.[Methods]The ethyl acetate fraction was isolated from ethanol extract from roots of M.philippinensis(Merr.et Rolfe)Li by silica gel column chromatography,and then the structures of the chemical constituents contained in it were identified by physicochemical property,TLC,UV,1H-NMR and13C-NMR.[Results]Three compounds isolated from the ethyl acetate fraction were respectively identified as genistein(I),5,7,2’,4’-tetrahydroxyisoflavone(II),and ourateacatechin(III).[Conclusions]Three compounds were isolated and identified from the ethyl acetate fraction of ethanol extract from M.philippinensis(Merr.et Rolfe)Li roots.
[Objective] To study the chemical constituents of ethyl acetate fraction of ethanol extract from Moghania philippinensis (Merr.et Rolfe) Li roots. [Methods] The ethyl acetate fraction was isolated from ethanol extract from roots of M.philippinensis (Merr.et Rolfe ) Li by silica gel column chromatography, and then the structures of the chemical constituents contained in it were identified by physicochemical property, TLC, UV, 1H-NMR and13C-NMR. [Results] Three compounds isolated from the ethyl acetate fraction were identified As genistein (I), 5,7,2 ’, 4’-tetrahydroxyisoflavone (II), and ourateacatechin (III). [Conclusions] Three compounds were isolated and identified from the ethyl acetate fraction of ethanol extract from M.philippinensis .et Rolfe) Li roots.
