Composition of fatty oils from Semen Ziziphi Spinosae and its cardiotonic effect on isolated toad hearts.
In this study, the composition of fatty oil from Semen Ziziphi Spinosae and its cardiotonic activity on the heart isolated from a toad were studied. Oil-in-water (O/W) emulsions of fatty oil were prepared by the perfusion method. The fatty oil had a positive inotropic effect on isolated rat hearts at a concentration between 5 × 10(-3) and 2 × 10(-2) mL/10 mL, and the effect was in positive correlation with the concentration of calcium ions. In addition, this effect was inhibited by 2 mg/mL nifedipine, suggesting that the cardiotonic mechanism could be responsible for accelerating the inflow of calcium ions. Gas chromatography-mass spectrometry analysis showed that the main constituents of the fatty oil were 9-octadecenoic acid (43.32%), 9,12-octadecadienoic acid (42.57%), h...
