The HPLC enantioseparation of the last generation antidepressive drug milnacipran (+/-)-1 was investigated on different cellulose-based chiral stationary phases (CSPs). On carbamate-type columns, Chiralcel OD and OD-H (+/-)-1 could be separated with alpha value about 1.20 but the resolution was quite low because of the tailing of the peaks. Direct determination of (+/-)-1 with high selectivity and resolution was obtained on Chiralcel OJ in normal phase mode elution. Precolumn derivatization of milnacipran with Fmoc-Cl gave compound (+/-)-2 which was enantioseparated on all the investigated CSPs and allowed enhanced UV or fluorimetric detection. The Chiralpak IB, that could be considered the immobilized version of Chiralcel OD-H, was found completely ineffective in the chiral recognition of (+/-)-1 and moderately efficient in the separation of (+/-)-2.
