“…Quaternary isoquinoline alkaloids are highly polar compounds and their analysis presents some special problems due to their strong interaction with the absorption sites of the stationary phase. The single berberine alkaloid has been quantified by HPLC in the in vivo plant (Dutschewska et al 1982) and also by using ion-pair HPLC in crude drugs and in pharmaceutical preparations (Akada and Tanase 1977;Hattori et al 1977;Akada et al 1980). The HPLC separation of quaternary alkaloids has been summarized by Verpoorte and Baerheim Svendsen in their review (1984).…”

“…1) is one of the most important bioactive compounds used in Chinese herbal drugs to evaluate the quality of the Phellodendron cortex. In earlier years, several methods including acetone-UV, 3 amberlite-UV, 4 TLC-UV, 5 gas liquid chromatography (GLC), [6][7] and high-performance liquid chromatography (HPLC) 5,[8][9][10][11] were used to determine the contents of berberine in some crude drugs. But owing to the complicated components in Chinese herbal drugs, the use of UV and HPLC methods may be restricted by the lengthy analysis and the presence of potentially interfering alkaloid components.…”
