This paper deals with the identification of seven snake-drugs by means of iso-electric point of protein. The experimental results show that different species of snake-drugs have different iso-electric points. The experimental data are accurate and easily reproducible (CV less than 0.5%). The difference of the averages of iso-electric points of the seven snake-drugs (P less than 0.01%) is extremely significant and thus provides a scientific criterion for the identification of peeled or powdered snake-drugs.
本文利用蛋白质的等电点对七种蛇药进行鉴别。实验结果表明，不同种类的蛇药具有不同的等电点。实验数据准确且易于重现（变异系数小于0.5%）。七种蛇药等电点平均值的差异（P小于0.01%）极为显著，从而为鉴别去皮或粉末状蛇药提供了科学依据。
