This study was performed to investigate the effect of Artemisiae argyi Herba extract on the treatment of chromaticity and colorfastness. Artemisiae argyi Herba has been used as a Korean medicine. It is effective in removing skin disorders and suppressing pain. It is also good as a fungicide and in treating pruritis. In the long history of Korea, dyeing has been applied for a means representing the grace of natural and inner esthetic consciousness of man. Vegetable dyes give us such great benefits, diversified color; but no pollution. And ramie fabric has distinctive features such as beautiful brilliance, elegance, and strong durability. So, it is regarded as a special product of Korea traditionally. These studies were carried out to treat with acetate iron, dichloride copper and alum with a mordant to ramie fabric. The ramie fabric was died with Artemisiae argyi Herba extract. The results of experiment showed as follows: First, the chromophoric degree was the highest in acetate iron but not distinction in another mordants. Seocond, the light colorfastness was the highest in non treated and dichloride copper, but alum was the lowest. Third, the discoloration was alum and dichloride copper showed first grade in washing colorfastness. Abrasion colorfastness was not significant in this test. According the previous results, Artemisiae argyi Herba has an efficiency in removing skin disorders and suppressing pain. So it is considered that Artemisiae argyi Herba can be applied effectively to theraphy of fungicide and in treating pruritis.

천연물로부터 새로운 항산화물질을 구명하기 위하여 국내에서 생산된 약용작물 38종을 수집하여 항산화 활성물질을 탐색한 결과 가시오갈피, 구절초, 건강, 목단, 시호, 산수유, 삼백초, 산사, 유근피, 작약, 천궁, 홍화씨, 및 황금등 13종이 항산화 활성이 높은 생약재로 선발되었다. 선발된 13종의 생약재중 홍화씨에 대한 활성물질을 추적, 분리하여 NMR로 물질구조를 동정한 결과 N-feruloylserotonin이 항산화 물질이라는 것을 처음 밝혀냈다. DPPH radical소거 활성에 의한 기존 항산화제인 α-tocopherol, BHA 및 BHT를 N-feruloylserotonin과 항산화력를 비교한 결과 N-feruloylserotonin이 6.6μg/ml로 활성이 가장 높은 것으로 밝혀졌다.
