Matrix solid-phase dispersion(MSPD) was developed for the extraction of four alkaloids, including aconi-tine, mesaconitine, hypaconitine and deoxyaconitine, from the roots of Aconitum kusnezoffii Reichb. The determina-tion of the analyte was carried out by high performance liquid chromatography with UV detection. The alkaline alu-mina was used as sorbent. The mixture of acetonitrile and water was used as elution solvent. Several extraction pa-rameters, such as type of sorbent, the ratio of sample to solid support material, type of the elution solvent and the vo-lume of the elution solvent were tested. Mean recoveries ranged from 93.16% to 102.73%, with relative standard deviations from 0.27% to 4.17%. With the extraction efficiency and time expenditure taken into account, MSPD ex-traction should be a comparatively good method.
