This study aim to compare the extraction yield, antioxidant potential, and chemical composition of Chaetoceros costatus extracted with acetone, ethanol, hexane. The freeze-dried diatom biomass was by ultrasonication for 1 h at 40 °C. capacity determined using 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging oxygen absorbance (ORAC), while profiles extracts were analyzed high-performance liquid chromatography high-resolution mass spectrometry electrospray ionization (UHPLC-ESI-HRMS). ORAC assay showed a 27% higher activity acetone extract, DPPH almost 3-fold inhibition. Pigments, fatty acids, sterols, their derivatives identified in all extracts. ethanolic acetonic did not differ significantly, hexane yielded fewest compounds. results this will contribute challenges that limit biotechnological application exploitation diatoms.
