摘 要:以鱼鳔为原料,采用酶法提取类肝素,研究其提取工艺参数和体外抗凝血活性。在单因素试验基础上,以加酶量、酶解时间和温度为影响因子,类肝素得率为响应值,采用响应曲面法优化鱼鳔类肝素(HSB)提取工艺,并通过测定活化部分凝血活酶时间(APTT)、凝血酶原时间(PT)和血浆凝血酶时间(TT)评价其抗凝血活性。结果显示,最优提取条件为2709碱性蛋白酶添加量5.4 mg/mL,酶解温度50℃,时间20h,在该条件下类肝素得率为(1.79±0.05)%,与预测值相差3.24%;同时,所提取的类肝素具有一定的抗凝血活性,并通过外源性凝血途径和共同凝血途径发挥作用。A natural heparin-like compound was isolated from swim bladder and its anticoagulant activities were determined.The response surface analysis based on Box-Behnken design was adopted to examine effects of protease consumption,extracting time and temperature on heparin-like compound extraction.The anticoagulant activity of swim bladder heparin-like compound was evaluated by APTT,PT and TT method.Consequently,the optimum conditions were as follows.The concentration of protease from Bacillus licheniformis was 5.4 mg/mL,extracted at 50 ℃for 20 h.Under the control of these conditions, the predicted extraction rate by mathematical model was(1.79±0.05)%,and the standard error was3.24%.In addition,the heparin-like compound from swimming bladder(HSB)showed negligible in vitro anticoagulant activity,and played a role through the exogenous coagulation pathway and the common coagulation pathway.
