摘要

In this work, high-performance liquid chromatography (HPLC) coupled with a hybrid quadrupole time of-flight mass spectrometry (Q-TOF-MS/MS) was used to study chemical compositions of different processed products of Rhizoma Anemarrhenae (RA). A Grace Alltima(TM) C-18 column (250x4.6mm, 5 mu m) was used for separation. Mobile phase consisted of 0.1% formic acid and acetonitrile, using gradient elution. ESI-MS data was acquired in both positive and negative mode. The experiment was established on the basis of a series of reference substances (two xanthone and seven saponins) to qualitatively identify the chemical compounds of different processed products of RA by MS analysis. There was no difference in the type of chemical constituents between different processed products of RA. A total of 25 compounds were identified, including four xanthones, 21 steroidal saponins and eight pairs of isomers. Copyright (c) 2015 John Wiley & Sons, Ltd.
