本文介绍了两个系列的两相溶剂体系，为系统地寻找适合高速逆流色谱的溶剂体系提供了方便。 正己烷-乙酸乙酯-正丁醇-甲醇-水体系提供了广泛的疏水性，而氯仿-甲醇-水体系对于具有中等疏水性的各种天然产物的分离非常有用。 这些溶剂系列的实际用途，其中包括二硝基苯基氨基酸，S-三嗪除草剂，吲哚生长素，和非离子有机溶剂的几个测试样品证明。
We have introduced two series of two-phase solvent systems which facilitate the systematic search for the solvent systems suitable for high-speed counter-current chromatography. The n-hexane-ethyl acetate-n-butanol-methanol-water systems provide a broad range of hydrophobicity, while the chloroform-methanol-water systems are extremely useful for separations of various natural products with moderate hydrophobicity. The practical use of these solvent series was demonstrated with several test samples which include dinitrophenyl amino acids, S-triazine herbicides, indole auxins, and non-ionic organic solvents.
