Macroalgae Sargassum cristaefolium Extract Inhibits Proinflammatory Cytokine Expression in BALB/C Mice

Table 2

Summary of bioactive compounds analysis based on MS¹ and MS². The exact mass of HRMS spectra was compared with the available database of METLIN, Scifinder, PubChem, and GNPS. The MS2 data were submitted to high-throughput dereplication comprehensive MS/MS libraries from GNPS (Supplementary Material, Figure S1–S6).
