摘 要:目的优选湿法超微粉碎提取水蛭的最佳工艺。方法在单因素试验基础上,以料液比、浸泡时间、提取温度和粉碎时间为自变量,根据Box-Behnken原理采用4因素3水平的响应面分析法,以抗凝血酶活性为响应值,对湿法超微粉碎提取条件进行优化。结果湿法超微粉碎提取水蛭的最佳工艺条件:料液比为1∶12,浸泡时间为4.9 h,提取温度为6.5℃,粉碎时间为12 min,其抗凝血酶活性达到20.13 U/g。结论湿法超微粉碎提取技术适用于水蛭的提取,本实验优选的提取工艺稳定可行,适于进一步推广应用。Objective To study the optimal extraction for Hirudo by wet ultrafine grinding technology. Methods On the basis of single-factor experiments, the response surface analysis was made for exploring the optimal extraction conditions by wet ultrafine grinding technology for Hirudo, with solid-liquid ratio, soaking time, extraction temperature, and grinding time as independent variable and the anticoagulant activity as the response value. According to Box-Behnken principles, the response surface analysis method with four factors and three levels was used. Results The optimum extraction condition for Hirudo by wet ultrafine grinding technology was as follows: solid-liquid ratio 1 : 12, soaking time 4.9 h, extraction temperature 6.5 ℃, grinding time 12 min; The anticoagulant activity could reach 20.13 U/g. Conclusion The extraction by wet ultrafine grinding technology for Chinese materia medica Hirudo is stable and feasible, and it could be further promoted.
