To establish amethod for identifying Shicangpu（Acori Tatarinowii Rhizoma）（ATR）from common counterfeits by ultra performance liquid chromatography（UPLC）technology，and to provide reference for quality evaluation and control of ATR.
Waters CORTECST3 column（2.1 mm×150 mm，1.6μm）was used.Methanol：acetonitrile 1：1（A）-water（B）solution was used as mobile phase and gradientelution was performed.The flow ratewas0.2mL/min.The column temperature was40℃.The detection wavelength was275 nm and the sample volume was3μL.The UPLC characteristic map was established to identify ATR from common counterfeits.
The UPLC characteristic map identified 4 common peaks of ATR and identified 1 of them.The similarity among samples was 0.892～0.996.
The established method of characteristic map is simple，reliable，accurate and repeatable，which can identify the authenticity of ATR directly，provide a specific method for the quality control and authenticity identification of ATR，and effectively improve the drug safety of related products.
