New rocaglamide derivatives from Vietnamese Aglaia species
Abstract:
Phytochemical analysis of the leaves of different Aglaia species collected in Vietnam yielded eight rocaglamide derivatives, which are responsible for the strong insecticidal activity against Spodoptera littoralis, including rocaglamide A (1), rocaglamide 1 (2), rocaglamide W (3), rocaglamide AB (4), rocaglamide J (5), rocaglaol (6), rocaglamide S (7) and the new rocaglamide AY (8). The structures of these compounds were elucidated through extensive 1D and 2D NMR spectroscopy and analysis of their mass spectrometric (ESI-MS) and HRESIMS data.
