Structural Characterisation and Identification of Phenylethanoid Glycosides from Cistanches deserticola Y.C. Ma by UHPLC/ESI–QTOF–MS/MS

Phenylethanoid glycosides (PhGs) are the major active constituents of Cistanches deserticola Y.C. Ma. However, the isolation, purification and identification procedures of PhGs are difficult and time-consuming.To establish a rapid and sensitive ultrahigh-pressure liquid chromatography (UHPLC)/ESI (electrospray ion source)-quadrupole time of flight (QTOF)-MS/MS method that could be applied to rapidly profile and identify PhGs.Seven standard...
