In vitro neuraminidase inhibition assays and ultrafiltration liquid chromatography with diode- array detector coupled to electrospray ionization tandem mass spectrometry (LC-DAD-ESI-MSn) were combined to screening neuraminidase inhibitors from Radix Scutellaria extract. As a result, Radix Scutellaria extract showed strong neuraminidase inhibitory activity, six compounds presented neuraminidase inhibitory effects were observed and identified by LC-DAD-ESI-MSn.

Key words: ultrafiltration LC-DAD-ESI-MSn, Radix Scutellaria extract, neuraminidase inhibitor
