title: A new sesquiterpene with a novel 1β, 8β-oxygen bridge from Heteropappus altaicus (willd.) Novopokr.
abstract: A new guaiane-type sesquiterpene, 4α,7β-dihydroxy-10βH-guai-5-en-1β,8β-endoxide (1), was isolated from Heteropappus altaicus (Compositea). The structure of compound 1, which contains exhibited a rare 1,8-oxide bridge, was established on the basis of spectroscopic data.
