| Abstract: | Three insecticidal sesquiterpene pyridine alkaloids with a beta-dihydroagarofuran sesquiterpene skeleton, euoverrine A (1), B (2), and euophelline (3), and a known compound, euojaponine C (4), were isolated from the root bark of Euonymus verrucosides, E. fortunei and E. phellomana by bioassay-guided fractionation. Their chemical structures were elucidated mainly by analyses NMR and MS spectral data. |
