초록

갈조류에서 에스트로겐 활성소재를 평가하기 위하여 in vitro 검출시스템을 사용하여 에스트로겐 효과를 가지는 분획을 검증하였다. 각각의 갈조류의 분획물들은 에탄올 추출로부터 물, 헥산, 부탄올 그리고 메탄올의 용매를 이용한 분획과정을 통해 제조하였다. 갈조류들의 수층 분획물에서 가장 높은 에스트로겐 활성을 보였다. 미역과 다시마의 수층 분획물들은 $500\;{\mu}g/ml$의 농도에서 $10^{-7}\;M$의 표준물질($17{\beta}$-estradiol)과 비슷한 활성을 보였으며, 곰피와 돌자반의 수층 분획물들은 $500\;{\mu}g/ml$의 농도에서 $10^{-8}\;M$의 표준물질보다 높은 활성을 보였다. 이 연구의 결과로 갈조류인 미역, 다시마, 곰피 및 돌자반의 수층 분획물에 에스트로겐 대체 작용을 할 수 있는 성분이 포함되어 있는 것을 확인하였으며, 이를 이용하여 폐경기 장애를 예방할 수 있는 에스트로겐 활성소재의 개발이 가능할 것으로 기대된다.

In order to evaluate estrogenic compounds in brown algae, an in vitro test system for the verification of estrogenic activity was applied. Fractions from ethanol extracts of each brown alga were prepared by a systematic fractionation procedure with solvents such as $H_2O$, hexane, butanol and methanol. Aqueous fractions of brown algae showed the highest estrogenic activities. Estrogenic activities of $500\;{\mu}g/ml$ aqueous fractions of Undaria pinnatifida and Laminaria japonica showed almost the same strength as that of $10^{-7}\;M$ standard solution ($17{\beta}$-estradiol). Furthermore, estrogenic activities of $500\;{\mu}g/ml$ aqueous fractions of Ecklonia stolonifera and Porphyra suborbiculate represented higher activities than that of $10^{-8}\;M$ $17{\beta}$-estradiol. These observations suggest that aqueous fractions of all these brown algae are expected to possess estrogenic compounds and could be developed as estrogenic agents for postmenopausal disorder.
