从生长于巴基斯坦卡拉奇沿岸礁石上的褐藻Spatoglossum variabile中分离得到2个新的肉桂酸酯(1、2)和3个已知化合物(3-5)。 将褐藻用水洗净,自然干燥后用甲醇浸泡1周,过滤,减压回收溶剂,得到的甲醇提取物(512g)用蒸馏水研碎,依次用正己烷、氯仿、乙酸乙酯和 Two new cinnamate (1,2) and 3 known compounds (3-5) were isolated from the brown algae Spatoglossum variabile grown on the reefs along the coast of Karachi, Pakistan. The brown algae were washed with water, naturally dried and then soaked in methanol for 1 week, filtered, and the solvent was recovered under reduced pressure. The resulting methanol extract (512 g) was triturated with distilled water, and hexane, chloroform, and ethyl acetate were successively used.
