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).
