The purpose of this study was to investigate the protective effect of total flavonoids from Dracocephalum moldavica L. (DML) on myocardial ischemia/reperfusion injury in isolated rat hearts. Male Wistar rats were randomly divided into three groups, Hearts were excised and attached to Langerdorff apparatus, Fluid of perfusion was Krebs-Henseleit with mixture of 95% oxygen and 5%carbondioxide. Left ventricular developed pressure (LVDP) and maximum up/down rate of left ventricular pressure (±dp/dtmax) were recorded as myocardial function by a Power Lab system. And the level of superoxide dismutase (SOD), malondialdehyde (MDA) and GSH/GSSG ratio were analyzed to determine the oxidative stress status in myocardial tissue. The level of MDA significantly decreased (P<;0.01) in DML group compared to the IR group, as well as the SOD activity (P<;0.01) and total glutathione (P<;0.05) increased the results implied that the DML has obviously protective effects in myocardial reperfusion injury.
