The extracts prepared from ten kinds of culinary and medical herbs (oregano, purple sage, golden lemon thyme, dark opal basil, sweet basil, arp rosemary, german chamomile, mullein, apple mint, and curry plant) were measured for total phenol, flavonoid1), DPPH free radical scavenging activity and TBA method. Extract solutions were used 70% methanol and distilled water. Total contents of phenol and flavonoid were following as : Oregano > purple sage > golden lemon thyme > apple mint. The extraction rate was high from the extraction solvent of 70% methanol. The DPPH free radical scavenging activity of herbs appeared most highly from the methanol and distilled water extract of oregano. When the concentration of the extract of oregano was increased, antioxidant activity was confirmed that it increased as well. But the effect of
lipid peroxdation detected a highly in dark basil. These results suggest that cultivars of herb can be considered as a steady natural antioxidative material.
