  Three xanthones from Polygala cyparissias

  摘要：

  The ethyl acetate extract of Polygala cyparissias afforded three unknown and three known simple xanthones. The structures of the former were established by spectroscopic methods as 1,7-dihydroxy-2,3-methylenedioxy-,1,3,6,8-tetrahydroxy-2,7-dimethoxy- and 1,3,7-trihydroxy-2-methoxyxanthone. Moreover, the hexane extract gave an uncommon sterol (alpha-spinasterol) and high yields of methyl salicylate. (C) 1998 Elsevier Science Ltd. All rights reserved.
