title: Sesquiterpenes from roots of Lingularia veitchiana.
abstract: Together with seven known sesquiterpenes, a new guaiane, a new furanoeremophilane, and a new eudesmane were isolated from the roots of Ligularia veitchiana. Their structures were elucidated by spectroscopic methods. The bioactivities of three known guaiane sesquiterpenes were determined.
