A sensitive fluorimetric method for the determination of octopine, a member of opine family, is presented. The method is based on the formation of a fluorescent derivative of octopine with benzoin and the separation by high performance liquid chromatography using a reversed-phase column (Kaseisorb LC ODS-300) within 20 min. The octopine derivative is completely separated from other guanidino compounds including arginine which is generally very high in marine invertebrates. This method gives higher sensitivity, 5 pmol minimum detection, and better reproducibility than the electrophoresis method and colorimetric method.
