  • Title: [A new HPLC procedure for cyclamate in food with pre-chromatographic derivatization].
    Author: Schwedt G, Hauck M.
    Journal: Z Lebensm Unters Forsch; 1988 Aug; 187(2):127-9. PubMed ID: 3223090.
    Abstract:
    A high-pressure liquid chromatography (HPLC) procedure for the detection of cyclamate in liquid and solid samples is presented, which depends on oxidation and the reaction of cyclohexylamine with o-phthaldialdehyde to form a condensation product. The results of the HPLC analysis, using an RP-C 18 separation system with UV detection at 242 nm are reported. Contents, from 2 to 400 mg/l, can be detected in less than 2 h (HPLC analysis within 20 min) with relative standard deviations of 4%. Only for cucumber infusions were incomplete recoveries of 68% obtained.
