  • Title: Capillary electrophoresis with field-enhanced stacking for rapid and sensitive determination of strychnine and brucine.
    Author: Zhang J, Wang S, Chen X, Hu Z, Ma X.
    Journal: Anal Bioanal Chem; 2003 May; 376(2):210-3. PubMed ID: 12692702.
    Abstract:
    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 with recovery of 105.1% for strychnine and 98.4% for brucine.
