[Simultaneous determination of 7 active ingredients in Scutellaria barbata D. Don by capillary micellar electrokinetic chromatography].

A method of capillary micellar electrokinetic chromatography with a diode array detector was developed for the simultaneous determination of 7 active ingredients (baicalein, naringenin, wogonin, scutellarin, apigenin, luteolin, and protocatechuic acid) in Scutellaria barbata D. Don and its ointment. The 7 ingredients in samples were extracted with methanol in an ultrasonic bath.
