초록
본 연구에서는 비교적 가격이 저렴하고 부작용이 없으면서 효능이 우수한 피부 노화 억제 제품을 개발하고자 먼저 다양한 종류의 약용식물을 대상으로 각종 유기용매 추출물을 제조한 후 이들의 elastase 저해 활성을 측정하여 우수 식물을 선발하고 이들로 부터 elastase 저해제 추출 최적조건을 검토하였다. 64종의 약용식물에 대한 다양한 추출물 가운데 복분자 메탄올 추출물의 elastase 저해 활성이 85%로 가장 높았고 이 저해물질은 메탄올로 50℃에서 12시간 진탕 시켰을 때 가장 많이 추출 되었다.
Abstract
To develop a new anti-skin aging cosmetics or functional foods by using elastase inhibitor, a potent elastase inhibitor was screened from various extracts of medicinal plants and its optimal extraction condition was investigated. Methanol extracts of Rubi fructus showed the highest elastase inhibitory activity of 85%. The elastase inhibitor of Rubi fructus was maximally extracted when it was treated with 80% methanol at 50℃ for 12hr and its elastase inhibitory activity(IC50) was 0.52 ㎎.
