PREPARATIVE SEPARATION OF ISOQUINOLINE ALKALOIDS FROM PHELLODENDRI CORTEX BY PH-ZONE-REFINING COUNTER-CURRENT CHROMATOGRAPHY
pH-Zone-refining counter-current chromatography (PZRCCC) was successfully used for preparative separation isoquinoline alkaloids from Phellodendri Cortex. Two target compounds of berberine and palmatine were completely resolved by a two-phase solvent system chloroform/methanol/water (4:2:2, v/v), wi...
