Selective Enrichment and Quantification of α-Asarone in Human Plasma by Dispersive Solid-phase Extraction with Fluorescence Detection
This work used a covalent organic framework TpBD-Me
2
(COF-TpBD-Me
2
) based dispersive solid-phase extraction fluorescence detection method to enrich and quantify
α
-asarone in human plasma. The optimal adsorption conditions of COF-TpBD-Me
2
on α-asarone were also investigated,including the mass concentration of adsorbent,adsorption time,pH,desorption solvent and desorption time. Furthermore,the adsorption behaviour and mechanism were elucidated by static adsorption and adsorption kinetics studies. α-asarone exhibited a good linear range of 0.1-10 μg/mL,with correlation coefficients(
r
2
) greater than 0.999,and the limit of detection(LOD) was 0.002 5 μg/mL. The proposed method applied for the α-asarone in actual human plasma samples for detection recoveries of spiked samples in the range of 92.2%-98.0% with relative standard deviations of 1.9%-3.8%. The results demonstrated that the method can effectively selectively enrich α-asarone in human plasma and accurate quantification. The methodology strategy provided a reference for the selective enrichment and rapid quantification of drug active ingredients in complex biological matrices.
