Abstract
Four flavonoids namely (2 R,3 R)-2,3- trans-7,4′-dimethoxydihydroflavonol, (2 R,3 S,4 S)-2,3- trans-3,4- cis-7,4′-dimethoxy-3,4-flavandiol, 6-hydroxy-7,4′-dimethoxyflavone, 6,7,4′-trimethoxyflavone, along with the known isoflavonoids ferreirin, dihydrocajanin, dalbergioidin, dihydrobiochanin A and biochanin A and other 11 known compounds were isolated from the roots of Gynerium sagittatum. The structural characterization of these compounds was carried out via one- and two-dimensional NMR experiments in combination with ESI-MS. Finally a quantitative analysis of the isoflavones of the methanolic extract was performed by LC-ESI-MS. The high quantity of isoflavonoids found in G. sagittatum makes this plant a good natural source of isoflavonoids.
