CE and CEC analysis of phytochemicals in herbal medicines

CE and CEC, due to their versatility and high efficiency, have attracted great interest in the analysis of phytochemicals in herbs and their preparations. Previously, we reviewed the analysis of phytochemical bioactive compounds by CE in 2006 (Electrophoresis 2006, 27, 4808-4819) or CEC in 2010 (Electrophoresis 2010, 31, 260-277). This review followed the previous studies and covered the literature published since 2006 for CE and 2009 for CEC (excluding those mentioned in the two previous reviews), which emphasized the development of CE and CEC techniques in phytochemical analysis. In addition, sample preparation and detection were also discussed.
