Natural Ginger extract was extracted from Ginger component using ethanol as a solvent, and we tested various pharmaceutical characteristics in this extract. Characteristics experiment to use natural Ginger extract tested antimicrobial experiment using microbe, and analyzed organic and inorganic component with analysis instrument. From the result of characteristics experiment, some conclusions are obtained as follow. In this experiment, natural Ginger extract was obtained about 22.50 g-Ginger extract(extraction ratio : 1.80%) as liquid state of some viscous yellow-brown color. The result of antimicrobial experiment with staphylococcus aureus and aspergillus niger in microbe decreased more and more according to passage of reaction time. This phenomenon could know that Ginger extract has influenced to antimicrobial effect. In the result of instrumental analysis, aromatic organic components of benzimidazole(1.283), propyl isothiocyanate or isothiocyanic acid(1.477) etcs from Ginger extract were detected with GC/MS and inorganic component of Ca(27.6 ppm), K(24.08 ppm), Mg(6.03 ppm), Na(1.02 ppm), Zn(1.02 ppm), Sb(0.711 ppm) and Li(0.079 ppm) etcs from Ginger extract were detected with ICP/OES.
