Article abstract of DOI:10.1016/0031-9422(90)85058-N

Three new isoflavones, 5,3'-dihydroxy-7,8,2'-trimethoxy-isoflavone, 5,3'-dihydroxy-2'-methoxy-6,7-methylenedioxyisoflavone and 5,3'-dihydroxy-6,7,8,2'-tetramethoxyisoflavone, have been isolated and identified from the roots of Salsola somalensis.These are found to possess an unusual 2',3'-oxygenation pattern. 1H and 13C NMR data are given for the compounds and their methyl ethers.
