• Ligustrazine
• 13-cyclodextrin
• Nitrogen-doped multi-walled carbon nanotube
• Electrochemical determination
• Ligusticum wallichii

In this work, beta-cyclodextrin and nitrogen-doped multi-walled carbon nanotube (NCNT) were directly incorporated to graphite powder, and an electrochemical treatment was implemented for the fabrication of a new sensor. The characteristics of the as-prepared electrode were studied using cyclic voltammetry (CV) measurement. Due to the synergic effects of beta-cyclodextrin and NCNT, the response of our developed sensor for ligustrazine was more significant than that of other electrodes. Our developed sensor exhibited excellent performance in the quantitative determination of ligustrazine in Ligusticum wallichii.
