Phytoactive substances were present in a culture broth of Drechslera gigantea, a pathogenic fungus of several grasses. Twelve eremophilane sesquiterpenes (1, 2, 3, 4, 6, 7, 10, 11, 12, 13, 14, and 15) were isolated and structurally characterized by a combination of single-crystal X-ray diffraction and spectroscopic analyses. Most of these sesquiterpenoids were phytotoxic; however, compounds 1 and 3 caused chlorophyll retention, an activity previously associated with phytohormones.
几种禾本科植物的致病真菌——巨座壳霉（Drechslera gigantea）的培养液中存在植物活性物质。通过单晶X射线衍射和光谱分析相结合的方法，分离并鉴定了12种紫穗槐烷倍半萜（1、2、3、4、6、7、10、11、12、13、14和15）的结构。这些倍半萜类化合物大多具有植物毒性；然而，化合物1和3可使叶绿素保留，这是一种先前与植物激素相关的活性。
