红藻门植物含丰富的、具有多种生物活性的代谢物。鸡冠枝藻属Lophocladia sp.红藻广泛分布于热带和亚热带地区。作者自斐济萨武萨武海域采集该属红藻样本,用乙醇保存,实验时以二氯甲烷-甲醇(2∶1)溶液萃取,得到具有细胞毒活性的有机粗提物。在硅胶柱上对其进行真空色谱处理,用R
Rhodophyta plants are rich in metabolites with various biological activities. The red alga of Lophocladia sp. is widely distributed in tropical and subtropical regions. The authors collected samples of the genus Rhodophyta from Savusavu Fiji and preserved them with ethanol. The experiment was performed with a dichloromethane-methanol (2:1) solution extraction to obtain crude organic extracts with cytotoxic activity. Vacuum chromatography on a silica gel column using R
