A simple, accurate and effective micellar electrokinetic capillary chromatography (MEKC) method for the separation and determination of protocatechuic aldehyde (PA), danshensu (DSS), salvianolic acid B (SAB) and gallic acid (GA) in Chinese medicine 'SHUANGDAN' granule was developed in this work. The separation was carried out in a 50.0 cm (42.0 cm to the detector) × 75 µm i.d. fused-silica capillary...
Cortex Moutan is one important traditional Chinese herb used in many traditional prescriptions. Paeonol (PN) and paeoniflorin (PF) are two active components contained in Cortex Moutan.
