title: Dammarane-type saponins from Ziziphus jujube.
abstract: Two new dammarane-type saponins jujubosides D and E, together with three known compounds, were isolated from the seeds of Ziziphus jujube. Their structures were elucidated on the basis of chemical and spectroscopic evidence. Compounds 1-5 showed lipoxygenase-inhibiting activity.
