Article abstract of DOI:10.1246/bcsj.57.2496

Four bitter quassinoid glycosides, shinjuglycosides A, B, C, and D were isolated from seeds of Ailanthus altissima SWINGLE and their structures were established to be 2-β-D-glycopyranosides of chaparrin, shinjulactone A, amarolide 11-acetate, and amarolide, respectively, from spectral data and enzymatic or acid-catalyzed hydrolysis.
