Objective To investigate the effect of Arnebia eutropha on killing Schistosoma japonicum cercariae. Methods Different concentrations of aqueous alkaloids were prepared and 100 μl of various concentrations were drawn on glass slides to observe the survival of cercariae and infection in mice at different times. Results The mortality of cercariae of Schistosoma japonicum was 97.71% and 100% respectively when the drug concentration was 2.5 and 5 mg / L for 60 min. The mortality of cercariae of Schistosoma japonicum was 10, 20 mg / L and 30 min respectively. Infectious. Conclusion Blood alkaloids do have a certain effect of killing Schistosoma japonicum cercariae
