title: Acutangulosides A-F, monodesmosidic saponins from the bark of Barringtonia acutangula.
abstract: Nine triterpene saponins, acutangulosides A-F (2-7), and acutanguloside D-F methyl esters (5a-7a) and a single triterpene aglycone (1) were isolated from a water extract of the bark of Barringtonia acutangula. Their structures were assigned on the basis of spectroscopic data.
