ABSTRACT

   Capillary electrophoresis (CE) is a newly developed instrument widely used with very good results in the analysis and separation of proteins, amino acids, peptides, organic acids as well as pharmaceuticals. It offers short analysis times, good reproducibility, autosampling, and is especially suitable for the analysis of high polar compounds. These characteristics lead to conjecture about possible application to analysis of Chinese herbal drugs. This paper describes the use of capillary electrophoresis in analysis of such crude drugs as Paeoniae Radix, Phellodendri Cortex, Coptidis Rhizoma, Ephedrae Herba, Scutellariae Radix and the Ephedrae Herbacontaining, Coptidis Rhizoma-containing, Phellodendri Cortex-containing, Scutellariae Radix-containing, Glycyrrhizae Radix-containing, Armeniacae Semen-containing Preparations.

Key words : Capillary Electrophoresis, Chinese-Herb Drugs, Chinese-Herb Preparations
