Abstract
Separation of the three groups of nucleosides: (1) Urd, ara-Urd, and dUrd; (2) Cyd, ana-Cyd, and dCyd; (3) Ado, ara-Ado, and dAdo are shown in graphs. There is a slight overlap between the ara-Urd and dUrd peaks. Separation of the group of nucleosides, Guo, ara-Guo, and dGuo was not studied because ara-Guo was not available. In all three cases, ribonucleosides were eluted first, followed by arabinonucleosides and deoxyribonucleosides. This is in accord with our concept of stability and formation of borate complexes. In ribonucleosides (I) the 2'- and 3'-hydroxyl groups are in the cis position, which facilitates the formation of a borate complex, whereas in arabinonucleosides (II) the 2'- and 3'-hydroxyl groups are in the trans position and complex less well with borate. The 2'-deoxyribonucleosides (III) lack vicinal hydroxyl groups and hence do not form borate complexes at all. The anions are excluded according to the amount of negative charge carried by them as a result of borate complexation. The order of elution is ribonucleosides, arabinonucleosides, and deoxyribonucleosides.
