Abstract

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.

Abstract

Four new hemiterpenoid derivatives, taxilluside A-D (1-4), were isolated from the branches and leaves of Taxillus chinensis (DC.) Danser. Their structures were determined on the basis of spectroscopic analysis. Of these compounds, compounds 3 and 4 showed inhibition activity on Calcium concentration in myocardial cells evaluated by measuring the changes of fluorescence signal using Laser scanning confocal microscope.
