Immunogenic antigen (jujuboside A-BSA) and coating antigen (jujuboside A-OVA) of jujuboside A were synthesized by sodium periodate oxidation method for the first time. Jujuboside A artificial antigen was confirmed by matrix-assisted laser desorption ionization/time-of-flight mass spectrometry (MALDI-TOF-MS). The titer and specificity of the antibody in serum of immunized mice were detected by enzyme-linked immunosorbent assay (ELISA). The corrected relation curve of inhibition rate showed that the antibody against Jujuboside A obtained from immunized mice could bind to jujuboside A and the titer was up to 1∶4 000. The jujuboside A artificial antigen was synthesized, which can be used further to preparation of monoclonal antibody and the pharmacokinetics study of jujuboside A in laboratory animals.
