초록
율무와 현율무의 total methanol 추출물과 분획 한 후의 각 획분에서의 DPPH 라디칼 소거작용 및 tyrosinase 저해작용을 검색 비교하여 그 함량-작용간의 dose-dependent한 결과를 얻었다. 라디칼 소거작용은 율무의 n-butanol 분획이 가장 활성이 높아 standard로 사용한 BHT의 6.7배 정도의 농도에서 같은
The seeds of Coix lachryma-jobi L. var. ma-yuen(yullmoo) were investigated for the free radical scavenging and mushroom tyrosinase inhibitory activities. Brown yullmoo, which contains bran in the seed, has also been evaluated for comparison. After partitioning of the total methanol extracts of yullmoo and brown yullmoo, each organic layer exhibited mild or potent dose-dependent inhibition(about 20-80%) on 1,1-diphenyl picryl hydrazyl(DPPH) free radical with the concentration of
