This experiment was carried out to search for changes of growth and pharmacological component contents by cultivation years in Artemisia capillaris. Percentage of ovenwintering in 1-year old was high as 95.3% but that in 2-years old was very low as 64.2%. Plant height was the highest in 2-years old among the treatments. By the way, number of stems and branches were shown wide difference by cultivation years, so those were the best in 3-years old. It was thought that 3-years old plants dispersed and used their nutrients by increasing branches. Fresh weight was the highest as 200.0 g in 3-years old, whereas weight of capitulum included scoparone, effective component, was the highest as 109.6 g in 2-years old and low as 96.4 g in 3-years old. In general components, crude protein and ash were more included in 1-year old and crude lipid and fiber were more included in 2 and 3-years old. Especially, content of crude fiber in stem was the highest in 3-years old. Pharmacological components were the most existed in capitulum of 2-years old, so contents of scoparone and capillarisin were 6.5 mg/g DW, 1.65 mg/g DW, respectively.
