Abstract Three new sulfated isoguanine alkaloid glycosides, locustosideAdisulfate(1) ,saikachinosideBdisulfate(2), andsaikachinosideAtrisulfate(3), have been isolated from the pupa lcase of the wild bruchid seed beetle Bruchidius dorsalis (Chrysomelidae,Bruchinae) infesting the seed of Gleditsia japonica Miquel(Fabaceae)along with the known compounds 9–11. Thestructures of the new compounds were determined through spectroscopic data and X-ray crystallographic analysis. The isolated compounds were evaluated for their inhibitory activity against starfish embryogenesis
