Identification of Flavonoids in Homeopathic Mother Tinctures of Galanthus woronowii Losinsk. And Galanthus nivalis L. by Ultra-Performance Liquid Chromatography with Photodiode Arrays and Tandem Quadrupole Mass-Selective Detectors

详细

The flavonoid profiles of homeopathic mother tinctures (HMT) from two snowdrop species – Woronow’s snowdrop (Galanthus woronovii Losinsk.) and the common snowdrop (Galanthus nivalis L.) – were determined by ultra-performance liquid chromatography with photodiode arrays and tandem quadrupole mass-selective detectors (UPLC/PDA/MS/MS). Flavonoid glycosides were identified in snowdrop HMT, whose aglycones were quercetin (0.075 ± 0.0047%% and isorhamnetin (0.043 ± 0.0028%) in Woronow’s snowdrop HMT and quercetin (0.029 ± 0.0026%) and kaempferol (0.011 ± 0.0009)% in common snowdrop HMT.
