  Xanthones from the stems of Securidaca inappendiculata

  摘要：

  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 dic chemotaxonomic significance of these findings are also discussed. (C) 2001 Elsevier Science Ltd.
