The metabolites from the coumarin and quercitin class, present in tissues of plants belonging
mainly to the Myrtaceae, Lamiaceae and Apiaceae families, included compounds with high
chemical diversity. These health-promoting components are recognized for their valuable
biological activities in herbal preparations but also for their phototoxic effects. A comparative
LCMS study to analyse the metabolite profile of Coriandrum sativum, Mentha piperita and
Eucalyptus citriodora was done. This analytical approach was applied to investigate the
metabolite compositions of leaves extracts obtained from Coriandrum sativum, Mentha
piperita and Eucalyptus citriodora. The individual compounds were tentatively annotated
using database correlations, retention time (Rt), accurate m/z data obtained by electrospray
ionisation (ESI) (+)?HR?MS, proposed molecular form, theoretical mass, mean concentration
in ppm and LCMS fragmentation patterns. Moreover, the identification was based on
transforming the exact mass ratio (m/z) for the protonated molecular ions [? + ?]+
of the
observed metabolites, which made it possible to graphically present the ion peaks. Caffeic
acid-hexose, Coumaric acid-hexose, Quercetin, Kaempferol, Naringenin, Dicaffeoylquinate and Tricaffeoylquinicate were reported in Coriandrum sativum belonging to Apiaceae family.
Salicylicate, Protocatechuic, Ferulicate, Sinapicate, Myricetin, and Astragalin were reported
in Mentha piperita belonging to Lamiaceae family. Vanillic acid Kaempferol, Rutinand
Malvidin-3-(caffeoyl)- rutinoside-5-O-glucoside were reported in Eucalyptus citriodora
belonging to Myrtaceae family.
