An antifeedant triterpenoid saponin has been isolated from the seed of Barringtonia asiatica and its structure elucidated mainly by two dimensional NMR spectroscopy is identified as 3-O-{[β-D-galactopyranosyl(1→3)-β-D-glucopyranosyl (1→2)]-β-D-glucuronopyranosyloxy}-22-O-[2-(E)-methyl-2-butenyloyloxy]-15, 16,28-trihydroxy-(3β,15α,16α,22α)-olean-12-ene. This compound showed antifeedant activity towards Epilachna sp larvae Keywords: Barringtonia asiatica, saponin, antifeedant
