Crude invertase was obtained from the water extracts of Korean ginseng, Panax ginseng C. A. Meyer, by fractionation with $0.8{\sim}1.0$ saturation of ammonium sulfate. The properties of the crude invertase were as follows: Crude invertase was stable in the pH range between 5 and 9, and at the temperature below $35^{\circ}C$. Crude invertase showed the optimum pH at 5.0 and the optimum temperature at $50^{\circ}C$. The activity of the crude invertase was inhibited by $Ag^{+}\;Mn^{+}\;Hg^{+}\;Zn^{+},\;and\;Rb^{+}$, while $Ca^{+}\;Cu^{+},\;and\;Fe^{3+}$ demonstrated remarkable increasing effects on the enzyme activity.
