New xanthone glycosides from Securidaca inappendiculata

Abstract
Three new xanthone glycosides, securixanside A ( 1 ), securixanside B ( 2 ), and securixanside C ( 3 ) were isolated from the stems of Securidaca inappendiculata . These compounds were characterized by spectrometric and chemical methods, including FABMS and one- and two-dimensional NMR experiments.
