Abstract

Two new quassinoids, shinjudilactone and shinjulactone C were isolated from the root bark of Ailanthus altissima SWINGLE and their structures were established to be 1β,11α-dihydroxy-2,16-dioxo-13(12→11α)abeo-picras-3-en-12,20-olide and 1α,12α : 5α,13α-dicyclo-1β,12β,20-trihydroxy-9βH-picras-3-ene-2,11,16-trione, respectively, by X-ray diffraction analysis. Shinjudilactone was prepared from ailanthone by benzilic acid rearrangement.
