우리나라 연안에 널리 분포하고 있는 지충이로부터 3개의 norisoprenoid 화합물들인 (+)-epiloliolide (1), (-)-loliolide (2), apo-9''-fucoxanthinone (3)을 칼럼크로마토그래피와 역상 HPLC를 사용하여 분리<TEX>$\cdot$</TEX>정제하였다. 이들 분리한 화합물 1, 2 및 3은 갈조류인 지충이로부터 처음 분리되어 보고하는 것이다. 특히 화합물 1은 비록 육상식물에서 분리된 바 있으나, 해양생물로부터는 처음 분리되어 보고하는 것이다. 분리된 화합물의 구조는 <TEX>$1^H$</TEX> COSY, NOESY, HMQC 그리고 HMBC와 같은 이차원적인 NMR 분광학적인 실험을 이용하여 문헌치와 비교하여 확인하였다. From Sargassum thunbergii which is widely distributed in coastal area of Korea, three norisoprenoids, (+)-epiloliolide (1), (-)-loliolide (2), and apo-9'-fucoxanthinone (3) were isolated by using column chromatography and reverse-phase HPLC. Compound 1, 2 and 3 were for the first time isolated from the Brown Alga Sargassum thunbergii. Particularly, Compound 1 was for the first time isolated the marine organism although it was reported from the terrestrial plant. Their structures have been determined by extensive 2-D NMR experiments such as <TEX>$^1H COSY, NOESY, HMQC$</TEX>, and HMBC and by comparison with the reported data in the literature.
