title: Three new diterpenoids based on the novel sarcopetalane skeleton from Croton sarcopetalus.
abstract: The roots of Croton sarcopetalus afforded three new diterpenoids (2-4) with a novel carbon skeleton that seems to be derived biosynthetically from a pimarane precursor. The essential oil of the roots gave trans-methylisoeugenol as the main constituent, along with 22 further compounds.
