title: Antifeedant activity againstSpodoptera litera larvae and [(13)C]NMR spectral assignments of the meliatoxins.
abstract: The tetranortriterpene, meliatoxin A2, induced a significant level of antifeedant activity inSpodoptera litura F. larvae, while meliatoxin B1, which lacks the ring D epoxide, was much less active. Complete [(13)C]NMR assignments for both compounds derived from homo- and heteronuclear short- and long-range couplings are given.
