Three new modified limonoids from Khaya senegalensis.
Three new rings B/D opened limonoids, two rearranged phragmalin limonoids named khayanolides D and E (1 and 2), and one limonoid glucoside named khayanoside (3) were isolated as insect antifeedants from the stem bark of Egyptian Khaya senegalensis. The structures of these compounds were established by spectroscopic methods, including 2D NMR and CD.
