【発明の詳細な説明】
〔産業上の利用分野〕
本発明は、アミノ酸などのカルボキシル基を含有する化
合物の混合物を液体クロマトグラフィーにより効率良く
分離する方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method for efficiently separating a mixture of compounds containing carboxyl groups, such as amino acids, by liquid chromatography.
アミノ酸などのカルボキシル基を含有する化合物の混合
物、例えば光学異性体の混合物を液体クロマトグラフィ
ーにより効率よく分離する方法については、これまでに
も種々研究されてきた。Various studies have been conducted on methods for efficiently separating mixtures of compounds containing carboxyl groups such as amino acids, for example, mixtures of optical isomers, by liquid chromatography.
しかしながら、従来提案されたものは何れも分離性能に
於いて満足すべきものではなかった。However, none of the methods proposed so far have been satisfactory in terms of separation performance.
本発明者らは、かかる問題点について鋭意検討した結果
、本発明を完成したものである。The present inventors have completed the present invention as a result of intensive study on such problems.
即ち本発明は、液体クロマトグラフィーにおいて、カル
ボキシル基を含有する化合物の混合物を順相系で分離す
る際に、酸を用いることを特徴とする分離方法に関する
。That is, the present invention relates to a separation method characterized in that an acid is used when separating a mixture of compounds containing carboxyl groups in a normal phase system in liquid chromatography.
本発明において、順相系とは移動相が固定相に比べて極
性の低い場合を順相系と呼び、例えば固定相にシリカゲ
ルを用い移動相にへキサン等を使用する場合などが例示
できる。In the present invention, a normal phase system refers to a case where the mobile phase has lower polarity than the stationary phase, and examples thereof include a case where silica gel is used as the stationary phase and hexane is used as the mobile phase.
本発明においてカルボキシル基を含有する化合物として
は、有機化合物の分子中にカルボキシル基を少なくとも
1個含有する化合物である。In the present invention, the compound containing a carboxyl group is a compound containing at least one carboxyl group in the molecule of an organic compound.
そしてその混合物としては、光学異性体からなる混合物
がある。例示するならば、光学活性なアミノ酸などがあ
る。The mixture includes a mixture of optical isomers. Examples include optically active amino acids.
また、幾何異性体、位置異性体などのその他の異性体か
らなる混合物がある。例示するならば、幾何異性体とし
てはシス−トランス異性体、オルト、パラ、メタ異性体
などがある。位置異性体としては、各種の環状多糖があ
る。その他、カルボキシル基を含有する種々の有機化合
物の混合物がある。There are also mixtures of other isomers such as geometric isomers and positional isomers. For example, geometric isomers include cis-trans isomers, ortho, para, meta isomers, and the like. Positional isomers include various cyclic polysaccharides. In addition, there are mixtures of various organic compounds containing carboxyl groups.
また本発明においては、カルボキシル基を含有する有機
化合物中にカルボキシル基以外の官能基があれば、分離
効率を上げるためそれを化学修飾しても□良い。Furthermore, in the present invention, if the organic compound containing a carboxyl group has a functional group other than a carboxyl group, it may be chemically modified to increase separation efficiency.
この様に本発明の分離方法は、種々の異性体、特に光学
異性体の分離に最適である。As described above, the separation method of the present invention is most suitable for separating various isomers, especially optical isomers.
本発明の分離方法に用いる充填剤としては、種々の溶媒
又はそれらの混合物を液体クロマトグラフィーの展開溶
