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...
