摘　　要：目的观察不同工艺提取的麻疯树籽油杀灭血吸虫尾蚴的效果,以筛选制备麻疯树籽油的最佳工艺及配方。方法采用6种不同工艺提取的麻疯树籽油,进行杀灭血吸虫尾蚴即时接触试验。采用麻疯树籽油及其与不同添加剂制成的制剂,进行昆明小鼠血吸虫尾蚴即时接触感染试验,观察其抗血吸虫感染的减虫率。结果 95%乙醇回流、料液比1∶8、2 h提取工艺出油率达30.7%。即时接触试验6种麻疯树籽油30 min内将尾蚴全部杀灭。即时接触感染试验麻风树籽油原液减虫率达70.97%,添加苯甲酸苄酯减虫率为58.87%,单一添加月桂氮酮减虫率达77.42%,添加苯甲酸苄酯、邻苯二甲酸二丁酯、月桂氮酮减虫率达100%。结论 95%乙醇回流、料液比1∶8、2 h提取工艺为麻疯树籽油最佳提取工艺。麻疯树籽油有较好的血吸虫尾蚴杀灭作用。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.
