Stewed Polygonati Rhizoma(SPR) is one of the famaous pieces of Jianchang Faction in Jiangxi province.we developed an analysis method with well separation and high stability to perform qualitative analysis.GC-MS was used to analyze the chemical components of the ethyl acetate extraction.The results showed that 31 compounds had been identified by NIST MS search 2.0 standard mass spectrometry Library and literatures.Next,UPLC-Q-TOF-MS was applied to identify the chemical components of the methanol extraction.The results showed that 12 compounds had been identified by search MassLynx workstation,ChemSpider,fragmentation regularity of mass spectrometry and literatures.This experiment will provide evidences for elucidation of the effective substance in SPR and can be used as a simple,shortcut method for analysis and identification for the Polygonati Rhizoma.
