This experiment was carried out to obtain the basic information on processing for product of high quality goods in Artemisia capillaris. We investigated antioxidant and antimicrobial activities by harvesting date and plant parts in Artemisia capillaris. Contents of total polyphenol compounds and flavonoids were the highest in leaf, followed by capitulum and stem. Leaf on June 30 contained 76.7 ㎎/g DW total phenolic compounds and 78.2 ㎎/g DW flavonoids. As RC50 value, that was, the concentration of sample required for 50% reduction of DPPH (2,2-diphenyl-1-picrylhydrazyl) absorbance, was very low as 5.42 ㎍ in leaf on June 30, antioxidant activity was the highest. In addition, RC50 of BHA, BHT and α-tocopherol were 3.09 ㎍, 24.30 ㎍ and 2.87 ㎍, respectively. And capitulum had antimicrobial activities against Bacillus subtilis, Staphylococcus aureus, Enterobacter aerogenes, Citrobacter freundii, Vibrio vulnificus, Pseudomonas aeruginosa, Saccharomyces cerevisiae. By the way, leaf and stem rarely had antimicrobial activity. Antimicrobial activities of capitulum according to harvesting date were very various. Capitulum on August 30 had the highest antimicrobial activities against Bacillus subtilis, Staphylococcus aureus, Vibrio vulnificus, Saccharomyces cerevisiae and on July 30 against Enterobacter aerogenes, Citrobacter freundii, Pseudomonas aeruginosa.
