A new capillary electrophoresis procedure with field-enhanced stacking concentration for the analysis of strychnine and brucine is established. After optimization of the separation and concentration conditions, the two alkaloids can be separated within 5 min and quantified with high sensitivity (The detection limits were 1.0 ng mL−1 for strychnine and 1.4 ng mL−1 for brucine). The method was useful for qualitative and quantitative analysis of strychnine and brucine in Strychnos nux-vomica L… 

Determination of Brucine in Strychnos by Capillary Electrophoresis

A capillary electrophoresis method has been developed for the determination of brucine in strychnos. The analytical conditions were optimized after investigating the effects pH and concentration of

Field-amplified sample stacking in capillary electrophoresis for the determination of alkaloids in Sinomenium acutum

An easy, rapid method for the simultaneous determination of isotetrandrine, curine, sinactine, sinomenine and magnoflorine in Sinomenium acutum was developed by a capillary electrophoresis (CE)

Capillary coated with graphene oxide as stationary phase for the separation of brucine and strychnine by capillary electrophoresis.

The developed capillary electrophoresis method provided an efficient separation of brucine and strychnine as well as a good reproducibility and stability and was successfully applied for the determination of these two alkaloids in a pharmaceutical formulation of traditional Chinese medicines.

Analysis of Natural Products by Capillary Electrophoresis and Related Techniques

Despite of obvious advantages, capillary electrophoresis (CE) is often considered as an alternative analytical technique only then if more established approaches such as HPLC fail to show

Voltammetric Behavior of Strychnine, and its Determination in Strychno Nux-Vomica Seeds Extract

Abstract.The voltammetric behavior of strychnine has been studied with a pyrolytic graphite (PG) electrode. The redox process taking place at the PG electrode is discussed. The cyclic voltammetric
