Isolation,Structure Determination, and Mode of Action of Insecticidal Compound from Barringtonia asiatica

One oleanane glycoside was successfully isolated from the seeds of Barringronia asiatica. The structure of this compound was determined by one- and two- dimensional ‘H-NMR and C-NMR and by direct comparison with standard compound. This compound showed the highest insecticidal activity against Crocidolonsia pavonana. We also examine the inhibitory activity of the active compound against some digestive enzymes, namely a-amylase, invertase and protease. The isolated compound did not show any inhibitory activity against any of the enzymes tested, on contrary, it increase the activity of protease. In conclusions, B. asiatica seeds have a very high insecticidal activity compound that is potential for natural insecticide application.
