Abstract: To accurately and quickly screen and identify trace alkaloids components from Semen Zizyphi spinosae,a HPLC online separation method of alkaloids components was developed using the columns which belong to the nitrogen-containing organic compounds (alkaloids) analysis kit.Then the alkaloids components separated on line were identified with the help of MassWorks molecular recognition software and LC-ESI-MS/MS.Three compounds:sanjoinine K (C17H19NO3),caaverine (C17H17NO2) and Nmethylasimilobine (C18H19NO2),belong to aporphine alkaloids and two compounds:sanjoinine F (C31H42N4O5) and sanjoinine A (C31H42N4O4),belong to cyclopeptide alkaloids were screened and identified.In addition,there was a pair of isomeric compounds:magnoflorine and zizyphusine (C20H24NO4),which belong to aporphine alkaloids to be further identified.A rapid and efficient screening method for alkaloids from Chinese medicine was established in this study.
