[The analysis of tiapride in cadaveric material]

To optimize conditions of tiapride isolation from cadaveric organs, we compared the results of conventional methods by Stas-Otto, A.A. Vasilyeva and V.F. Kramarenko which provide tiapride isolation up to 50% and a new precise and reproducible method providing 60 +/- 2% tiapride isolation. Identification of tiapride isolated from cadaveric material was made with thin-layer chromatography and high performance liquid chromatography. The latter assay employed the method of external standard. The original techniques proposed identify and measure tiapride in hepatic samples in the presence of unidentified endogenic compounds. The techniques are rapid, selective, sensitive and reproducible.
