从索马里猪毛菜(Salsola somalensis)根中分离并鉴定了3个新的甾酮化合物:5,3 "-二羟基-7,8,2“-三甲氧基甾酮,5,3”-二羟基-2“-甲氧基-6,7-亚甲二氧基甾酮和5,3”-二羟基-6,7,8,2“-四甲氧基甾酮。这些被发现拥有一个不寻常的2 '',3 ''-氧化模式。给出了化合物及其甲醚的~ 1H和~(13)C NMR数据。
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.
