Xanthones with anti-tumor activity isolated from Securidaca inappendiculata
Medicinal Chemistry Research, 2014A new xanthone, 1,2-dihydroxy-6,7,8-trimethoxyxanthone, together with ten known xanthones and nine other compounds was isolated from the stem of Securidaca inappendiculata. The structure of the new compound was elucidated based on spectroscopic data analyses, and other compounds were identified by comparison with data from the literature.

Xanthone isolated from Securidaca longependunculata with activity against erectile dysfunction
Fitoterapia, 20041,7-Dimethoxy-2-hydroxy-xanthone and 1,4-dihydroxy-7-methoxy-xanthone isolated from Securidaca longependunculata were tested for their activity on rabbit corpus cavernosum in vitro. Only the former relaxed the corpus cavernosum by 63% at 1.8 x 10(-5) mg/ml.
