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.
