Muchimangins G-J, fully substituted xanthones with a diphenylmethyl substituent, from Securidaca longepedunculata.

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.
