WebLink]
METHODS AND RESULTS:
Ten known tetranortriterpenoids,nimbin(1),Deacetylnimbin(2),salannolide(3),azadirachtin(4),vepaol(5),isovepaol(6),3 tigloyl azadirachtol(7),1 tigloyl 3 acetyl azadirachtinin(8),3 tigloyl azadirachtinin(9),1 tigloyl 3 acetyl 11 hydroxymeliacarpinin(10),were isolated from the seed kernels of Azadirachta indica .Their structures were identified on the basis of spectral methods.
CONCLUSIONS:
The extracts containing 0.5% azadirachtin and above ten tetranortiterpenoids show significant insecticidal activity to Plutella xylostlla L.and Piers rapae L.
