Three new sulfated isoguanine alkaloid glycosides, designated as saikachinoside A monosulfate ( 1 ), saikachinoside A disulfate ( 2 ), and locustoside B disulfate ( 3 ), have been isolated from the pupal case of the wild bruchid seed beetle Bruchidius dorsalis (Chrysomelidae, Bruchinae) infesting the seed of Gleditsia japonica Miq . (Fabaceae). Their structures were determined by spectroscopic methods and the inhibitory activity of 2 and 3 against acid phosphatase was evaluated.
