摘要 目的研究绿藻基根硬毛藻Chaetomorpha basiretorsa的化学成分,从中寻找结构特殊的化合物供活性筛选。方法利用正相和反相柱色谱、Sephadex LH-20柱色谱以及反相HPLC等技术进行分离纯化,借助MS、IR和NMR等方法鉴定结构;通过MTT法对单体化合物进行细胞毒活性筛选。结果从基根硬毛藻中分离鉴定了3个倍半萜类化合物和3个降碳倍半萜类化合物,分别为2-(1,2-二甲基-双环[3.1.0]环己烷-2-基)-5-甲基-苯酚(Ⅰ)、4-溴-2-(1,2-二甲基-双环[3.1.0]环己烷-2-基)-5-甲基-苯酚(Ⅱ)、海兔阿普里素(Ⅲ)、6α-羟基-紫罗-4,7-二烯-3,9-二酮(Ⅳ)、3β-羟基-5α,6α-环氧-β-紫罗烯酮(Ⅴ)、(3R,6R,7E)-3α-羟基-紫罗-4,7-二烯-9-酮(Ⅵ)。结论所有化合物均为首次从本属植物中分得,其中Ⅳ、Ⅴ为首次从绿藻中分离得到,Ⅵ为首次从海洋生物中分离得到。
