Supervised statistical analysis OPLS-DA score plots of metabolomic data of 28 soft coral extracts based on their cytotoxicity against three different cancer cell lines: (a) Human cervical cancer, SiHa, (b) human lung adenocarcinoma, A549, and (c) human prostatic carcinoma, PC3. Red dots indicate active extracts, and green dots represent extracts that were not active. An extract was considered active if it exhibited an inhibition of the tumor cell lines ≥ 50% at 20 μg/mL mL) [22]. The ellipses indicate confidence intervals of 95%.
