Two eudesmane sesquiterpenes from Laggera pterodonta

The phytochemical study of the aerial parts of Laggera pterodonta afforded two new eudesmane sesquiterpenes, 3α,4β,11-trihydroxyenantioeudesmane (pterodontriol E) (1) and 4β,8β,11-trihydroxyenantioeudesmane (pterodontriol F) (2), along with seven known compounds. Their structures were elucidated on...

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