Abstract: The manuscript make a qualitative analysis on chemical components in water extract of Angelicae Pubescentis Radix by HPLC-ESI-Q/TOF-MS;LC-MS/MS,C18(4.6mm×250 mm,5μm)column was adopted,with methanol-0.1%formic acid as the mobile phase for gradient elution;ESI ion source was used for mass spectra, and data were collected in positive and negative mode.twelve compounds from water extract of Angelicae Pubescentis Radix were identified by analyzing positive and negative ion mass spectra information and element composition and comparing controls with data from relevant literature,these provide powerful therapeutic material basis for water extract of Angelicae Pubescentis Radix.

Key words: water extract of Angelicae pubescentis Radix, chemical components, HPLC-ESI-Q/TOF-MS
