Objective:To investigate the antioxidant effects of water extract of Carthamus tinctorius L.on injury of cardiomyocytes induced by hydrogen peroxide(H
2
O
2
) and to detect reactive oxygen species(ROS) for exploring the mechanisms.Methods:In cultured neonatal rat cardiomyocytes
the antioxidant effect of water extract of Carthamus tinctorius L.was investigated after H
2
O
2
(1 mmol·L
-1
) induced damage.The spontaneous beating
the survival rate and release of LDH
MDA
SOD
NO
NOS
GSH-Px and XOD enzyme activity in supernatant were investigated
and cell suspension was collected for detecting reactive oxygen species(ROS) by electron spin resonance(ESR).Results: Preconditioning by water extract of Carthamus tinctorius L.increased the spontaneous beating and the survival rate
and decreased the release of LDH
MDA and SOD with the rise of SOD
NO
NOS and GSH-Px enzyme activity
while in the cell suspension ROS signal decreased significantly.Conclusion: Water extract of Carthamus tinctorius L.has antioxidative effect.The mechanisms are likely related with scavenging of free radicals
