摘要
Four new dammarane-type triterpene glycosides, named jujubosides I-IV (1-4), were isolated from Ziziphi Spinosae Semen, along with seven known saponins (5-11). The structures of new compounds were established on the basis of extensive spectroscopic analysis. All compounds were evaluated for the effects on neonatal rat cardiomyocyte injury induced by hydrogen peroxide in vitro.
