摘要:

The application of capillary electrophoresis (CE) to the separation and determination of the two active ingredients, magnolol and honokiol, inMagnolia officinalisand its processed product was described. Optimum separation was achieved with a fused-silica capillary tube(60.5cm × 75μm I.D.) and a Na2B4O7-NaH2PO4buffer(20 mmol/L) at pH=9.0 containing 20% of methanol. The applied voltage was 20 kV and the capillary thermostating temperature was kept constant at 25 deg;C.
