Mono-, di-, tri-ethanolamines and di-, tri-ethylamines were used to prepare phosphate buffer at pH 2.5 and shown to be capable of enhancing the separation selectivity of chiral drug pinacidil and melittin in bee venom in capillary zone electrophoresis. The reason is due to the reduction of the average apparent mobilities of the analytes.

Two capillary electrophoresis methods were developed for the determination of the active constituents in four anti-hrpertensive *** active constituents are nitrendipine and atenolol in Tabellae Nile, and hydrochlorothiazide, amiloride hydrochloride, captopril, and enalapril maleate in three other tablet formulations,respectively. The internal standard method was employed for quantitation with RSD between 1 .2~4.3%, recoveries ranging from 93. 1 ~ 101 .0%.

A micellar electrokinetic chromatographic (MECC) method with sodium cholate as pseudostationary phase was proposed for the separation and quantitation of two analgesic formulations containing acetaminophen, dextro-methorphan hydrobromide, phenylpropanolamine hydrochloride, and chlorpheniramine maleate. The internal standard method was proved to be able to yield satisfactory results even with a modular CE instrument with RSD between 0.6 similar to 2.1%, and recoveries ranging from 98.1 similar to 99.9%.

Cyclodextrin-modified CZE was applied to the chiral separation of two basic drugs, i.e., esmolol and terazosin. Selector screening and concentration optimization experiments were performed. Resolution 3.1 for esmolol, 1.2 for terazosin were achieved when using 60 mmol/L gamma-CD and 60 mmoL/L DM-P-CD, respectively, in 50 mmol/L pH 2.5 sodium phosphate buffer.
