Abstract

Chemical investigation on the roots of Securidaca inappendiculata resulted in the isolation of three new xanthones, Securixanthones E, F and G. Their structures were characterized as 7-hydroxy-1,2-dimethoxyxanthone (1), 1,7-dihydroxy-2-methoxyxanthone (2), 3,7-dihydroxy-1,2,8-trimethoxyxanthone (3), respectively, on the basis of spectral evidence.
