Abstract

This study was carried out to compare the biological activities of Epjmedium koreanum Nakai grown wild in Korea and China. The antioxidative effect of E. koreanum Nakai-extracts grown wild in Gangwondo was 78%, which was higher than that in China as 71%. The inhibition ratio of growing cancer cells was estimated as 89, 91 and 86% for human liver, lung and breast cancer cell lines, respectively in adding 0.1 g/l of ethanol extracts of E. koreanum grown in Korea. The hepatoprotective effect and Angiotensin Converting Enzyme (ACE) inhibiting effect of Korean one were also observed as 124 and 87%, respectively, which were also higher than those produced in China. There was not much difference between Korean and Chinese one in inhibiting ${\alpha}-glucosidase$ activities in all ranges of supplement. It was proved that most effective extraction solvent was mixed type as water and ethanol (1:1, v/v) to have higher biological activities from both Korean and Chinese ones.

강원도에 자생하는 삼지구엽초와 중국산 삼지구엽초 추출물의 생리활성을 결정한 결과는 다음과 같다. 1. 삼지구엽초의 항산화활성은 국내산이 중국산보다 높게 나타났으며, 추출용매는 증류수와 에탄올 1:1 혼합용매 추출물에서 78%로 가장 높은 활성을 보였다. 2. 간암, 폐암, 유방암 세포에 대한 생육억제능은 국내산에서 각각 85, 91, 85%로 나타났으며 이 추출물을 0.4g/L 이하의 농도로 투여 시 정상세포의 생존율은 70% 이상으로 유지되어 세포독성이 낮았으며 국내산이 중국산 보다 면역증진능이 높고 혼합용매 추출물에서 254%의 활성을 나타냈다. 3. 삼지구엽초 추출물들에서는 돌연변이원성이 나타나지 않았고 항돌연변이성은 낮게 나타났다. 4. 간 기능 증진효과는 국내산이 124%의 활성을 보여 중국산보다 높았다. 5. 고혈압 관련인자의 작용에서 국내산이 중국산보다 관련효소(ACE)에 대한 활성억제율이 높았고, 혈당 상승 관련효소 $({\alpha}-glucosidase)$에 대한 활성억제율은 87%였으나 국내산과 중국산 간에는 차이가 없었다. 6. 이러한 결과로 국내산 삼지구엽초는 중국산에 비해 항산화, 항암, 간 기능 증진, 고혈압 억제효과 등의 생리활성이 높아 생약으로서의 활용성이 더욱 높은 것으로 판단되었다.
