Koryoˇ(918-1392) made a certain progress in her culture and agriculture except the latter part of the era when the development in social economy were retarded due to military dictatorship and Mongol invasion. Despite of these external conditions, cultivations and kinds of horticulture foods were expanded with the help of many king`s agriculture first policy and the advancement in cultivating method. Among the horticulture foods, fruits such as peach, plum, Japanese apricot, apricot, cherry, pear, persimmon, pomegranate, crab apple, jujube, grape, Chinese quince, walnut, orange, yuzu, chestnut, ginkgo nut(silvernut), pine nut, nutmeg nut, and jat were growed, and vegetables such as Chinese cabbage, turnip, radish, garlic, welsh onion, gynmigit, scallion, taro, malva, cucumber, white gourd, bottle gourd, water melon, eggplant, Japanese ginger, ginger and litchi were cultivated, while seri, water shieled and bamboo sprouts were taken in natural. Fruits were taken in natural or through dry, and particularly grapes were used to make wine. Flowers of Japanese apricots, some fruit trees, and chrysanthemum were also made into wine. Certain fruits were used as medicine owing to its medicinal nature. Vegetables were used to make kimchi or to boil soup, sometimes they were dried to be kept in storage to be used in rare season and also used as medicine. Increase in kinds of horticulture foods does not have any direct relation with the reform of social economy, but the fact that so many kinds of horticulture foods were cultivated and used in Koryoˇ era shows that they elevated people`s life and dietary culture.

본 연구에서는 풍선덩굴 잎 추출물 및 그 분획물에 대하여 항산화 활성 평가와 성분 분석을 수행하였다. 본 실험에는 풍선덩굴 건조 잎의 50% 에탄올 추출물, 에틸아세테이트 분획 및 아글리콘 분획을 사용하였으며, 각각의 수율은 16.4, 0.9 및 0.3%로 나타났다. 자유라디칼 소거활성(1,1-diphenyl-2-picrylhydrazyl, DPPH, FSC50)은 에틸아세테이트 분획(92.5 μ g/mL)이 가장 큰 것으로 나타났으며, 이때 대조군인 (+)-α -tocopherol의 FSC5은 8.9 μ g/mL이었다. Fe3+-EDTA/H2O2계를 이용한 활성산소 소거활성(총항산화능, OSC50)은 아글리콘 분획(4.2 μ g/mL)에서 가장 크게 나타났으며, 대조군인 L-ascorbic acid (1.5 μ g/mL)와 유사한 효과를 나타내었다. 1O2로 유도된 사람 세포 손상에 대한 보호효과 측정에서 풍선덩굴 잎 추출물 및 분획 은 모두 농도 의존적(5.0-25.0 μ g/mL)으로 세포보호효과를 나타냈다. 추출물/분획물 중에서 아글리콘 분획 (τ50, 76.4 min)이 가장 큰 세포보호효과를 나타내었다. TLC, HPLC, LC/ESI-MS를 이용하여 풍선덩굴 잎 추출물 중 에틸아세테이트 분획물에 대하여 성분 분석을 실시하였다. 그 결과, apigenin-7-O-glucuronide, apigenin-7-glucosdie 및 quercitrin hydrate 등의 플라보노이드가 함유되어 있음을 확인하였다. 이상의 결과 들은 풍선덩굴 잎 추출물 또는 분획이 항산화 기능성 화장품 원료로서 응용 가능성이 있음을 시사한다.
