Three phenolic acids (gallic, 3,4-dihydroxybenzoic, and ellagic acids) and four hydrolyzable tannins (punicalin, punicalagins A and B, and corilagin) have been determined in pomegranate beverages and different parts of the fresh fruit and tree by liquid chromatography with diode array detection coupled to electrospray ionization and time-of-flight mass spectrometry (LC-DAD-ESI-ToFMS). For the...
A rapid approach for the determination of eight flavonoid aglycone compounds, baicalein, hesperitin, fisetin, naringenin, chrysin, myricetin, quercetin and kaempferol, in honey samples and related products has been optimized and validated. The enriched extracts obtained by dispersive liquid–liquid microextraction (DLLME) were analyzed by liquid chromatography with diode array detection coupled to...
