Özet

The qualitative and quantitative determination of phenylethanoid glycosides in methanolic extracts of five species of the genus Phlomis (Lamiaceae) has been investigated using a new reversed-phase HPLC method combined with photodiode-array detection and electrospray/MS analysis. Forsythoside B, verbascoside, samioside, alyssonoside, isoverbascoside, leucosceptosides A and B and martynoside were detected. The quantification of the above constituents was performed using echinacoside as internal standard. Knowledge of the content of phenylethanoid glycosides contributes to the chemotaxonomy of the genus. Copyright (C) 2005 John Wiley Sons, Ltd.
