HPLC fingerprints,to provide reference for quality evaluation Thlaspi arvense L.[Methods]HPLC chromatography was used,HPLC column Acclaim~ 120C_(18)( 250 mm × 3. 0 mm,5 μm),mobile phase of acetonitrile-0. 2% phosphoric acid aqueous solution gradient elution,flow rate of 0. 7 m L/min,column temperature of 30 ℃,detection wavelength of 320nm; the chromatographic fingerprint similarity evaluation software( Version 2004 A) was used for similarity evaluation and data processing on 10 origin Thlaspi arvense L. spectra,and the median method was used to generate control Thlaspi arvense L. fingerprint. [Results] The similarity of 10 origin Thlaspi arvense L. spectra was greater than 0. 90,19 common peaks were separated from different origin Thlaspi arvense L. and isovitexin,apigenin,luteolin and acacetin were identified. [Conclusions] The established HPLC fingerprint contained a lot of information and showed good specificity for Thlaspi arvense L.,which can provide a scientific basis for Thlaspi arvense L. quality evaluation system.展开更多
