title: New pseudoguaiane derivatives from Inula aschersoniana Janka var. aschersoniana.
abstract: The aerial parts of Inula aschersoniana Janka var. aschersoniana afforded parthenolide, diepoxycostunolide, inusoniolide, chrysosplenol C and four new pseudoguaiane-type sesquiterpenoids. Their structures were determined using spectral methods and relative stereochemistry by NOESY correlations.
