Abstract
Chemical investigation on the whole plants of Liatris elegans resulted in the isolation and identification of the new ferulic acid ester (1) and arylnaphthalene lignan (2), together with 13 known compounds. The structures of the new compounds were established as p-hydroxyphenylferulate (1) and 5,3'-dihydroxy-4,4'-dimethoxy-2,7'-cycloligna-7,7'-diene-9,9'-lactone (2) by extensive NMR and HRESIMS spectroscopic analyses.
