Flow-gated capillary electrophoresis (CE) is a hybrid of conventional and microchip CE since it employs a fused silica capillary as the separation channel while taking advantage of the well-controlled flow-gated injection, which adds versatility in terms of separation efficiency, analytical throughput, and ease of coupling with sample pretreatment procedures.

The separation of six isoflavones (biochanin A, isoformononetin, formononetin, prunetin, daidzein and genistein) and coumestrol on an uncoated fused-silica capillary electrophoresis column was optimised using alkaline borate buffer as electrolyte and DAD detection. A baseline separation of all analytes except a pair, formononetin-biochanin A was achieved at pH 10.5 in 25 min. Detection limits were low (0.1 µg/ml) and the linearity of the detector response was established in the concentration range 0.4–60 µg/ml (180 µg/ml for coumestrol). Coumestrol was synthesized and the carbon signals in 13C-NMR spectrum of both coumestrol and di-O-acetylcoumestrol were assigned for the first time using two-dimensional HMQC technique.
