title: The use of high-performance liquid chromatography in the quality control of oxytocin, vasopressin and synthetic analogues.
abstract: Optimized C18 reversed-phase systems for oxytocin, desamino-oxytocin, lysine-vasopressin, ornithine-vasopressin and felypressin with gradient elution are discussed, focussing on precision, selectivity and ruggedness of the methods. Data from collaborative studies are presented, demonstrating the equivalence of high-performance liquid chromatography (HPLC) assays to bioassays. The findings suggest that HPLC is an excellent alternative to the time-consuming and less reliable animal testing.
