Cis and trans isomers of tramadol hydrochloride were separated by capillary zone electrophoresis (CZE) in a fused-silica capillary with 40 mmol/L of borate as a carrier. The sample concentration-peak area plots were straight lines in the range 10-250 g/mL for both isomers. Based on the electropherog
Ferulic acid in extracts of raw herbs was separated by capillary zone electrophoresis in the buffer solution of 10 mmol/L Na(2)B(4)O(7). The simple and rapid method was linear, ranging from 5 to 100 microg/mL, and had a good reproducibility with the RSD below 2%. The contents of ferulic acid in Ange
