A capillary electrophoresis (CE)-potential gradient detection (PGD) method was developed for quick and sensitive determinations of puerarin, farrerol and baicalin. The flavonoids were baseline separated in 1.9 min with a buffer comprised of 20 mM tris(hydroxymethyl)aminomethane (Tris) and 3 mM HCl at pH 8.69. The analysis time is, to the best of our knowledge, the shortest for the CE analysis o...
