Abstract
AbstractA capillary electrophoretic method for simultaneous determination of six bioactive ingredients (berberine, palmatine, baicalin, sennoside B, emodin, and sennoside A) in the Chinse herbal formula San‐huang‐hsieh‐hsin‐tang was established. A carrier composed of aqueous buffer solution (50 mM sodium cholate, 15 mM sodium dihydrogen phosphate, and 4.25 mM sodium borate)‐acetonitrile (3:2) was found to be the most suitable electrolyte for this separation. Contents of these constituents in a non‐pretreated methanol‐water extract of San‐huang‐hsieh‐hsin‐tang sample could be easily determined within 20 min. The effects of borate, cholate, and organic modifier (acetonitrile) concentration of the carrier on the migration behavior of the solutes were also studied.
