1.催产素和加压素都为九肽，加压素分子中有一碱性氨基酸残基，两者等电点不同。催产素等电点为7.7，加压素等电点为10.9，即加压素碱性较强。将含有这二种激素的提取液通入人造沸石柱时，加压素易形成带正电离子而绝大部分被吸附，催产素通过沸石柱而流出。流出的催产素溶液，用皂土处理，可得较纯的催产素。
垂体后叶干粉提取↓水分离↓沸石柱去杂蛋白↓乙酸
皂土吸附↓皂土解吸↓乙酸催产素
将垂体后叶干粉100g和石英粉约30g加入蒸馏水1.4L中，于球磨中球磨提取45min，离心，收集上层清液。残渣再分别加水1.4L、1.3L、1.3L按上法再提取3次。将4次离心上清液合并。将处理好的人造沸石1500g，加入0.25%醋酸溶液20L，搅拌后装入交换柱中，待交换柱中0.25%醋酸液下降到沸石表面以下2～3cm处时，立即加入提取液，适当调节流速，收集吸附柱开始流出的白色浑浊液。当提取液液面下降到沸石表面时，立即续加蒸馏水，待浊液流尽后停止收集。流经沸石的提取液用冰醋酸调节pH=3.5，再用水浴迅速加热至95℃保持3min，立即冷却，0～5℃冷室放置过夜。次日过滤，得澄清滤液。然后将滤液在搅拌下，加入事先处理好的10%皂土浆（一般每100ml加3ml），连续搅拌1h，上清液应检查吸附是否完全（以20%磺基水杨酸溶液检查，应不发生沉淀），如吸附不完全，应再加皂土浆吸附。2次皂土沉淀合并。再将皂土用1%醋酸溶液解吸。总用量为5L分4次解吸，用量分别为1.6L、1.4L、1.2L和0.8L，合并4次解吸液。测定解吸液中催产素和加压素的含量，按催产素效价计算，如加压素未超过限度，即得催产素溶液。
