Abstract:
The chemical constituents of antiavian influenza virus (AIV) fractions from
Dryopteris Crassirhizoma were investigated using high performance liquid chromatography-tandem mass spectrometry (HPLC-MS
n). 52, 38 and 20 chromatogram peaks were detected using HPLC-MS
n in (+)ESI, (-)ESI and (+)APCI modes, respectively. The result showed that most constituents of anti-avian influenza virus (AIV) fractions from
Dryopteris Crassirhizoma were phlorophenone derivatives. Fourteen phlorophenone derivatives from
Dryopteris Crassirhizoma were identified and characterized basing on MS
n data. The results of this paper provided available data for further studies on anti AIV constituents and fingerprint of
Dryopteris Crassirhizoma .
