In order to investigate the possible use of spices as natural preservatives) antimicrobial activities of garlic and ginger, representative spices, were examinated. Distilled components of garlic and ginger were also analyzed. Each extract of garlic was more suppressive on the growth of Gram negative bacteria than that of Gram positive bacteria. Extracts of garlic were showed effective suppressions on the growth of yeasts. Of the extracts of garlic, ether extract was highest among antimicrobial activities. In the case of ginger, ether extract of ginger was effective for growth inhibition of tested bacteria. Distilled components of garlic and ginger were extracted by simultaneous steam distillation extraction apparatus. The concentrates were analyzed with GC/MSD and Kovat's retention index and identified 13 components and 21 components respectively. Distilled components of garlic and ginger were full of sulfur compounds and hydrocarbons, respectively. di-2-Propenyl disulfide, methyl 2-propenyl disulfide, 2-vinyl-4H-1,3-dithiirane and 3,3'-thiobis-1-propene were major principal aroma compounds in garlic. ${\alpha}-zingibirene$, ${\beta}-phellandrene$, ${\beta}-sesquiphellandrene$ and camphene were major principal compounds in ginger.
