Xanthone derivatives from Cratoxylum cochinchinense roots

Xanthones and caged-prenylated xanthones, named cochinchinones A–D, a synthetic known caged-prenylated xathone and seven known xanthones were isolated from the roots of Cratoxylum cochinchinense. Some of the compounds exhibited effective antioxidative properties. Two xanthones and two caged-prenylat...

Description
Summary:Xanthones and caged-prenylated xanthones, named cochinchinones A–D, a synthetic known caged-prenylated xathone and seven known xanthones were isolated from the roots of Cratoxylum cochinchinense. Some of the compounds exhibited effective antioxidative properties. Two xanthones and two caged-prenylated xanthones, named cochinchinones A–D, respectively, and a synthetically known caged-prenylated xanthone, together with seven known compounds were isolated from the roots of Cratoxylum cochinchinense (Lour.) Blume. Their structures were assigned on the basis of analyses of spectroscopic data. Some of the compounds exhibited effective antioxidative properties.
