Abstract
The ethyl acetate extract of Polygala cyparissias afforded three unkno wn and three known simple xanthones. The structures of the former were established by spectroscopic methods as ethylenedioxy-,1,3,6,8-tetrah ydroxy-2,7-dimethoxy- and 1,3,7-trihydroxy-2-methoxyxanthone. Moreover , the hexane extract gave an uncommon sterol (alpha-spinasterol) and h igh yields of methyl salicylate. (C) 1998 Elsevier Science Ltd. All ri ghts reserved.
