摘　　要：为了研究柱状角孔珊瑚(Goniopora columna)水螅体的次级代谢产物,采用硅胶柱层析、凝胶柱层析及半制备高效液相色谱对柱状角孔珊瑚水螅体粗提物中次级代谢产物进行分离纯化,利用现代波谱技术鉴定其结构,并对获得的次级代谢产物进行非小细胞肺癌A549细胞(non-small cell lung cancer A549 cells, NSCLC)的抗癌活性筛选。结果表明,从柱状角孔珊瑚水螅体中分离鉴定出8种化合物,分别为alkalgoniopora A (1)、茶碱(2)、胸腺嘧啶脱氧核糖核苷(3)、尿嘧啶(4)、胸腺嘧啶(5)、pregna-5,20-dien-3β-ol(6)、cinnamicacid(7)和原儿茶酸(8),其中化合物1为新发现的生物碱。初步细胞毒活性测试显示,化合物1、2和6对NSCLC增殖有较弱的抑制活性,其余化合物对NSCLC增殖无明显抑制活性。In order to investigate the secondary metabolites in hydranth of coral Goniopora columna,the ethanol extracted products were isolated and purified by silica gel column chromatography,Sephadex LH-20 gel column chromatography and semi-preparative high-performance liquid chromatography(HPLC).Their structures were identified by modern spectral technology.Meanwhile,the cytotoxicities of 1~8 were tested against anti-non-small cell lung cancer A549 cells(NSCLC)lines.As a result,a new alkaloid 1 and seven known compounds 2~8 were isolated and identified as alkalgoniopora A(1),theophylline(2),thymine deoxyribonucleoside(3),uracil(4),thymine(5),pregna-5,20-dien-3β-ol(6),cinnamic acid(7)and protocatechuic acid(8).Among them,compounds 1,2 and 6 had weak inhibitory activity on the proliferation of NSCLC,while other compounds had no obvious inhibitory activity on the proliferation of NSCLC.This investigation provides a reference basis for the study of metabolites and exploration of medicinal activity in hydranth of coral Goniopora columna.
