예로부터 삼지구엽초는(Epimedium koreanum Nakai)는 한방에서 강장, 강정, 이뇨 등의 약재로 이용되어 왔다. 본 연구에서는, 삼지구엽초의 주성분인 icariin의 함량에 따른 항돌연변이 및 면역활성을 탐색하여 향후 기능성 식품소재로서 활용하고자 하였다. Ames test 결과, icariin 함량에 따른 삼지구엽초 추출물은 TA98 및 TA100 균주 모두에서 집락수가 음성대조군에 비하여 농도 변화에 따른 집락수의 큰 변화를 나
Epimedium koreanum Nakai is a wild herb commonly consumed in South Korea due to its beneficial health effects. In the present study, the antimutagenic and immunoactivities of extracts from E. koreanum Nakai containing different icariin quantities were investigated for food use. In the Ames test, both the water and ethanol extracts were found not to have a mutagenic effect on Salmonella typhimurium TA98 and TA100, respectively. The E. koreanum Nakai extracts showed over 80 and 90% antimutagenic effects on benzo()pyrene (B(a)P) in S. typhimurium TA98 and TA100, respectively. Moreover, all the extracts showed over 70% antimutagenicity on S. typhimurium TA98 and TA100 against 4-nitroquinoline-1-oxide (4NQO). The E. koreanum Nakai extract with ethanol showed strong antimutagenic activity, higher than that of the water extract and the sequenced KE9412, KE9408, and KE9405. In the immunomodulating activity test, the effect of E. koreanum Nakai on the B (Rhamos) and T (Jukat) cells were investigated. The immunoactivity results showed that the growth and viability of the B and T cells increased and were activated more in KE9405 (1.8 times), KE9408 (1.6 times), and KE9412 (1.32 times) in the water extracts, and least in KE9412 (1.74 times), KE9408 (1.52 times), and KE9405 (1.4 times) in the ethanol extracts. In the case of both the water and ethanol extracts () from E. koreanum Nakai, the highest cell number of the human B (Rhamos) and T (Jukat) cells was observed on day 4 in KE9405 and KE9412, and on day 5 in KE9408. Based on the obtained results, the development of E. koreanum Nakai as a food material is recommended.
