Objective: To analyze the chemical constituents of 95%ethanol extract of Semiaquilegiae Radix by using HPLC-ESI-Q-TOF-MS. Method: C18 column (4.6 mm×150 mm
5 μm) was adopted
with acetonitrile-0.1% formic acid as the mobile phase for gradient elution; ESI ion source was used as mass spectra
and the data were collected in the positive mode. The mass scanning range was between m/z 50-1 500. Result: Eleven components were identified from 95%ethanol extract of Semiaquilegiae Radix by analyzing mass spectra information
and comparing with data from relevant literatures. Conclusion: Based on HPLC-ESI-Q-TOF-MS technology
relative molecular mass and spectrometry pyrolysis data were determined
and chemical components of Semiaquilegiae Radix were determined by literature analysis and retrieval. This study provides powerful evidence for further studying the pharmacodynamics material basis of Semiaquilegiae Radix.
