A new keto-dammarane type of saponin jujuboside G (1), along with three known triterpene saponins, jujuboside A (2), jujuboside B (3) and jujuboside A₁ (4), was isolated from the seeds of Zizyphus jujuba Mill. Var. spinosa Hu. The structures were established by spectroscopic methods (IR, 1D-, 2D-NMR, and HR-ESIMS).
