  Ichthyotoxic sesquiterpenes and xanthanolides from Dittrichia graveolens

  摘要：

  The ichthyotoxicity of Dittrichia graveolens was found to be due to the major sesquiterpenes 12-carboxyeudesma-3,11(13)-diene and tomentosin. In addition, seven structurally related sesquiterpenes and two new xanthanolides were isolated and their structures elucidated.
