title: Two eudesmane sesquiterpenes from Laggera pterodonta.
abstract: The phytochemical study of the aerial parts of Laggera pterodonta afforded two new eudesmane sesquiterpenes, 3alpha,4beta,11-trihydroxyenantioeudesmane (pterodontriol E) (1) and 4beta,8beta,11-trihydroxyenantioeudesmane (pterodontriol F) (2), along with seven known compounds. Their structures were elucidated on the basis of spectroscopic data.
