Abstract:
From the stems of Securidaca inappendiculata, securixanthones A (1,3,7-trihydroxy-2,8-dimethoxyxanthone) and B (3,7-dimethoxy-4-hydroxyxanthone) along with ten known xanthones were isolated. Their structures were elucidated by analysis chemical and spectroscopic evidence, and the chemotaxonomic significance of these findings are also discussed.
