Abstract:
Objective To evaluate the effect of Jatropha see soma japonicum so as to screen the optimum process and formulations. Methods The cercaria directly contacting tests with Jatro-pha seed oils extracted by 6 different extraction processes were carried out,and the mouse immediate contacting cercaria infection trials with different formulations of Jatropha seed oil and various additives were performed. Results With 95%ethanol,the ratio of material to liquid being 1∶8,and 2 h extraction,the oil extraction rate was 30.7%. The cercaria directly contacting tests showed that 6 kinds of Jatropha seed oil killed all cercaria within 30 min. In the mouse immediate contacting cercaria infection trials,the worm declined rate of Jatropha seed oil liquid was 70.97%,and the worm declined rate of the sample added with benzyl benzoate was 58.87%,and the worm declined rate of the sample added with laurocapram was 77.42%. The worm declined rate of the sam-ples added with benzyl benzoate,dibutyl phthalate and laurocapram was 100%. Conclusion The process with 95%ethanol,the ratio of material to liquid being 1∶8,and 2 h extraction is the optimum,and the Jatropha seed oil has a good killing schistosome cercaria effect.
