A sensitive, rapid and selective liquid chromatography-tandem mass spectrometry (LC-MS-MS) method was developed and validated for the simultaneous determination of baicalin, baicalein, wogonin, berberine, palmatine and jatrorrhizine in scutellaria-coptis herb couple in rat plasma. After protein precipitation with acetonitrile and
