title: Three new oleanane triterpenoid saponins acetylated with monoterpenoid acid from Albizia julibrissin.
abstract: Three new minor oleanane triterpenoid saponins acetylated with monoterpenoid acid, julibroside J(32), julibroside J(35) and julibroside J(36), along with one new natural product, prosapogenin 9, were isolated from the stem bark of Albizia julibrissin. Their structures were elucidated on the basis of the chemical and spectroscopic evidences.
