摘要 为了制备安全性高、副作用小的凝血酶抑制肽,将蛋清Alcalase酶解产物经凝胶柱色谱Sephadex G-50凝胶柱色谱和半制备高效液相色谱纯化,旋转蒸发、冷冻干燥后经酶标仪法检测其抗凝血活性,筛选出高抗凝血活性的组分。结果表明:经Sephadex G-50纯化后的第4个组分即洗脱时间为35~40min的组分抗凝血活性最好,抑制率达到84.74%。将该组分通过半制备高效液相色谱纯化后得到12个峰,峰Ⅶ即洗脱时间为17.275~19.542min的组分活性最高,抑制率达到71.27%。 为了制备安全性高、副作用小的凝血酶抑制肽,将蛋清Alcalase酶解产物经凝胶柱色谱Sephadex G-50凝胶柱色谱和半制备高效液相色谱纯化,旋转蒸发、冷冻干燥后经酶标仪法检测其抗凝血活性,筛选出高抗凝血活性的组分。结果表明:经Sephadex G-50纯化后的第4个组分即洗脱时间为35~40min的组分抗凝血活性最好,抑制率达到84.74%。将该组分通过半制备高效液相色谱纯化后得到12个峰,峰Ⅶ即洗脱时间为17.275~19.542min的组分活性最高,抑制率达到71.27%。
