Abstract

The structure of a new bitter principle, shinjulactone A, isolated from Ailanthus altissima SWINGLE was determined to be 11β,20-epoxy-1β,2α,11α,12α-tetrahydroxypicrasa-3,13(21)-dien-16-one and the configuration of a hydroxyl group at C-12 of ailanthone was revised to α-orientation by X-ray analysis.
