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.
