Objective: To define the structure of a water-soluble compound (SY-A) extracted from Dioscorea zingiberensis and investigate its protective effect against the neonatal rat cardiomyocytes ischemia/reperfusion (I/R) injured.
Methods: The SY-A was isolated from Dioscorea zingiberensis by utilizing column chromatograph and its structure was identified by 1H-NMR, 13C-NMR, 135DEPT. Neonatal rat cardiomyocytes were cultured and divided into 5 groups randomly.
