三角藻(Sargassum tortile)的水溶性部位含有抗肿瘤物质,而苯溶性部位含有刺激游动的幼虫置身于这种植物的物质,通过层析法从苯溶性部位已分得δ-tocotrienol(Ⅱ)和它的环氧化物。作者从醚溶性部位分得一种新的酚性物质 Sargatriol,为淡黄色油,C_(27)H_(38)O_4,[α]_D+16°(氯仿)。紫外最大吸收335毫微米(ε2560),添加醇性 KOH 后移到355毫微米处,表明存在酚性苯乙烯系统。核磁共振谱显示有1个叔甲基,4个烯甲基,1个苯甲基,2个
The water-soluble fraction of Sargassum tortile contains antineoplastic substances, while the benzene-soluble fraction contains material that stimulates swim-walking larvae to colonize this plant. The δ-tocotrienol (Ⅱ) And its epoxide. The authors obtained a new phenolic compound, Sargatriol, as a pale yellow oil, C 27 H 38 O 4, [α] D + 16 ° (chloroform) from the ether soluble fraction. The maximum UV absorption was 335 nm (ε2560), which shifted to 355 nm with the addition of alcoholic KOH, indicating the presence of a phenolic styrene system. Nuclear magnetic resonance spectrum showed a tert-methyl, 4 alkene, a benzyl, two
