17-beta-D-Glucopyranosides of limonin, obacunone, deacetylnomilin, nomilin, deacetylnomilinic acid, nomilinic acid, isolimonic acid, ichangin and 19-hydroxydeacetylnomilinic acid were isolated from sour orange seeds. The aglycone of the latter compound is a possible intermediate in the biosynthesis of limonin.
