Four highly oxygenated xanthones, muchimangins G-J (1-4), have been isolated from the roots of Securidaca longepedunculata collected in Democratic Republic of Congo. Their structures were elucidated by analyses of spectroscopic data to be fully substituted xanthones with a diphenylmethyl substituent at C-2.
四种高度氧化的紫檀烷类化合物，即木槿苷 G-J（1-4），从刚果民主共和国采集的长梗三叶木槿的根部分离得到。通过光谱数据分析，阐明了它们的结构，这些化合物均为全取代紫檀烷类化合物，在 C-2 位具有二苯甲基取代基。
