摘　　要：以牛初乳为原料,利用超滤、离子交换层析、凝胶过滤层析技术对其中抗高血压成分的提取工艺进行了研究。通过多次重复凝胶过滤层析,使终产物的含盐率大大降低,应用原子吸收分光光度计对终产物Na含量进行分析,最终产物含盐量达到了细胞实验可以接受的水平。Take bovine colostrums as raw materials, methods antihypertensive factor was purified by ultrafiltration, ion exchange chromatography, and gelatin filtration chromatography. Through duplicates the gelatin filtration chromatographic analysis many times, causes the end product to be salt-bearing rate reduces greatly, carries on the analysis using the atomic absorption spectrophotometer to the end product Na content, the end product salt content had achieved the cell experiment may accept level.
