Annotation Method Details Information

Title Characterization by compound database search and FlavonoidSearch
Description Database searching

Compound database searching was performed using the accurate mass value and the estimated adduct. The following databases are used: KEGG, KNApSAcK, Human Metabolome Database (HMDB), LipidMAPS, flavonoid database in The UC2 database in the MFSearcher web service (Sakurai et al., 2018, Bioinformatics 34: 698-) was used for rapid cross-database searching and compiling the constitutional isomers in one record.


Prediction of flavonoid aglycones was conducted by FlavonoidSearch (Akimoto et al., 2017, Sci Rep 7: 1243 ) using MS2 and MS3 spectra in positive mode. The possibility of the peak being a flavonoid is high when a higher hit score, usually larger than 0.3, is observed. Candidates of known flavonoids are listed in the FlavonoidSearch results.
