title: Isolation of a new tremorgenic indoloditerpene, 1'-O-acetylpaxilline, from Emericella striata and distribution of paxilline in Emericella spp.
abstract: The distribution of a tremorgenic mycotoxin, paxilline (1), was investigated in 19 species belonging to the genus Emericella. It was found that Emericella desertorum, E. foveolata, and E. striata produced paxilline (1). A new type of indoloditerpene, emindole DA (4), was also found in E. quadrilineata. A new tremorgenic indoloditerpene, 1'-O-acetylpaxilline (3), was isolated from the mycelium of E. striata. Its structure was established on the basis of spectroscopic investigations.
