OBJECTIVE
To explore the mechanism of protective effects of salvianolic acids and Panax notoginseng saponins and their combination on cardiomyocytes suffered with hypoxia-reoxygenation (HR) injury.
METHODS
HR-injured H9c2 cell was employed as cellular model to evaluate cardioprotective effects of
Four new triterpenoid saponins named clematangosides A-D (1-4) along with six known saponins (5-10) were isolated from the whole plants of Clematis tangutica. Their structures were determined by extensive spectral analysis and chemical evidences. All saponins were evaluated for their protective
