An antifeedant saponin has been isolated from the seeds of Barringtonia asiatica and its structure elucidated mainly by two dimensional NMR spectroscopy to be 3-O-{[β-D-galactopyranosyl(1→3)-β-D-glucopyranosyl(1→2)]-β-D-glucuronopyranosyloxy}- 22-O-[2-methylbutyroyloxy]-16, 28-dihydroxy-(3β,16α, 22α)-olean-12-ene.
