Structural characterisation and screening of triterpene saponins in the bark of Ilex rotunda using high‐performance liquid chromatography coupled to electrospray ionisation and quadrupole time‐of‐flight mass spectrometry

Introduction The bark of Ilex rotunda (BIr) has been used as a traditional Chinese medicine for a long time in China. Triterpene saponins (TSs) were considered to be the major bioactive ingredients and possessed antiplatelet aggregation activity. Identification of TSs in BIr is a necessary step to understand the biological properties. Objective This article describes a method for the rapid identification of TSs in BIr. Method An analytical...
