Abstract
由4種大型海藻與2種海濱植物單離之成分, 經各種光譜分析與化學方法鑑定其構造式如下: 1. 厚緣藻 D-mannitol (DOM-1), fucosterol(DOME-1),pachydictyol A (DOME-2), isopachydictyol A (DOME-3),dictyol E (DOM-4), isodictyol E (DOME-5), dictyol C (DOME-6),10-acetyldictyol C (DOME-7), 10-methoxydictyol E (DOME-8), 4a-hydroxy-dictyolactone (DOME-9), 6,7-epoxy-4-hydroxydictyolactone(DOME-10), 6,7-epoxyfukurinolal (DOME-11), deacetyldictyol H(DOME-12a), 14-epideacetyldictyol H (DOME-12b), (-)-loliolide(DOME-13), (+)-epiloliolide (DOME-14), 4a-hydroxycrenulide(DOME-15), 4a-acetoxycrenulide (DOME-16), crenulacetal C(DOME-17).2. 圈扇藻 D-mannitol (ZDM-1), fucosterol (ZDME-2),fucosterol 與脂肪酸形成的酯類化合物 (ZDME-1), 24-hydroperoxy-24-vinyl-cholesterol(ZDME-3), 5',7'-dihydroxy-2'-pentadecylchromone(ZDME-4).3. 日本沙菜 trans-phytol(HJ-1), 三個甘油脂質.4. 角網藻由角網藻分離出六種固醇類CSMS-1~CSMC-65. 海芙蓉 CC-1~CC-8.6. 林投分離得到11個化合物POME-1~POME-11共65個化合物
