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.
