피부 주름개선 소재개발을 위한 식용작물의 최종당화산물 생성 억제활성

국문 초록 (Abstract)

피부의 주름은 노화과정의 결과로 유도되어지는데, 비효소적 glycation 반응은 주름생성의 원인 중에 하나로 단백질의 비가역적 가교결합에 의해 생성된 최종당화산물(AGEs)이라고 불리는 갈색화합물을 생성한다. 비교적 반감기가 긴 collagen은 쉽게 glycation이 일어나고 collagen의 가교결합(cross-linking)이 일어나면서 여러 단계의 반응을 거쳐 최종적으로 생성된 AGEs가 피부에 축적되어 피부의 탄력감소 및 주름을 일으킨다고 알려져 있다. 피부 내에 glycation된 collagen의 축척은 피부의 탄력성을 유지하는 것을 방해 한다. 수종의 식용작물로부터 항주름소재를 개발하기 위하여 메탄올 및 열수추출물을 조제한 후 AGEs 형성을 억제하는 활성을 검색하였다. 먼저 서양향신료 중에서는 월계수잎, 계피, 정향, 오레가노, 로즈마리, 사보리, 팔각과 한약재 중에서는 복분자, 달개비, 삼지구엽초, 가자와 해당화의 메탄올 및 열수추출물에서 최종당화산물 생성 억제활성이 높았다. 그러나 국내 식물 중에서는 단지 참취 및 녹차 추출물의 메탄올과 열수추출물만이 높은 활성을 보였으며 해조류 중에서는 활성이 높은 시료는 없었다.

다국어 초록 (Multilingual Abstract)

Skin wrinkles typically appear as a result of aging processes. One of causes may be the nonenzymatic glycation followed formation of browning products called advanced glycation endproducts (AGEs), an irreversible cross-linked protein. The accumulation of glycated collagen cross-linked in skin inhibits the formation and function of skin tightening agents such as collagen and elastin. To development for anti-wrinkle ingredients from edible plants, MeOH and hot-water extracts were prepared and evaluated for their inhibitory effects of AGEs formation. The activities of both extracts from bay laurel (Laurus nobilis), cinnamon (Cinnamomum loureirii), clove (Eugenia caryophyllate), oregano (Origanum vulgare), rosemary (Rosemarinus officinalis), savory (Satureja hortensis) and star anis (Illicium verum) of western spices, and blackberry (Rubus coreanus), dayflower (Commelina communis), Epimedium koreamun (whole), termunalia frutus (Terminalia chebula) and turkestan rose (Rosa rugosa) of medicinal plants were higher than the others. Of Korean vegetables, however, MeOH and hot-water extract from only Asters caber and green tea showed higher activities, and no activity in Korean marine plants (seaweeds).
