Abstract: An HPLC method has been developed for the determination of the toxicity of organotin compounds in peanut oil, water or diet mixtures as test compounds. According to the formulation, the tin compounds were diluted or extracted with propan-2-ol or methanol and portions were applied to reversed-phase columns (Spherisorb and Hypersil) with mobile phases of mixtures of acetonitrile, water, acetic acid and LiCl. Post-column derivatization was carried out with morin and the organotin complexes were determined fluorimetrically. No peak interferences were observed and the coefficient of variation were generally 5%. Results were in good agreement with those by AAS.
