Abstract
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.
사철쑥 (Artemisia capillaris Thunb.) 재배년수별 생육과 약리성분 함량을 조사한 결과 월동률은 1년생은 95.3%이었으나 2년생은 64.2%로 매우 저조하였다. 초장의 경우 2년생은 123.8 cm로 가장 높았다. 그러나 경수와 분지수는 재배년수에 따른 차이가 크게 나타나 3년생에서 높았다. 3년생은 2년생에 비해 분지수는 많은 반면 초장은 낮았는데 이는 분지의 발달에 따라 영양분이 분산되어 사용되었기 때문으로 추측되었다. 생체중은 3년생에서 200.0 g으로 가장 높았다. 그러나 유효성분인 scoparone이 많이 함유되어 있는 종실의 무게는 2년생에서 109.6g로 높은 반면 3년생은 96.4g으로 낮았다. 일반성분의 경우 1년생은 조단백과 조회분이 많고 2, 3년생은 조지방과 조섬유가 많았으며 특히 줄기의 조섬유 함량이 3년생에서 높았다. 약리성분 함량은 2년생 종실에서 가장 높았는데 scoparone은 6.5mg/g DW, capillarisin은 1.65mg/g DW이 함유되어 있었다.
