HPLC Determination of Diperodon Enantiomers in Blood Serum by Using TeicoplaninChiral Stationary Phase
HPLC stanovenie enantiomérov diperodonu v krvnom sére s použitím teikoplanínovejchirálnej stacionárnej fázy
Na separáciu enantiomérov diperodonu bola použitá chirálna stacionárna fáza na báze teikoplanínua polárna-organická mobilná fáza v zložení metanol/acetonitril/kyselina octová/trietylamín45/55/0,3/0,2 v/v/v/v. Vypracovaná metóda bola vhodná na stanovenie enantiomérov v krvnom sérepri koncentráciách nad 0,5 µg/ml. Na štúdium degradácie enantiomérov diperodonu bola použitá invitro metóda a boli vypočítané experimentálne rýchlostné konštanty.

Overview
The chiral stationary phase on the base of teicoplanin and the polar-organic mobile phase methanol/acetonitrile/acetic acid/triethylamine 45/55/0.3/0.2 was used for the separation of diperodonenantiomers. The developed method was suitable to determine the enantiomers in blood serum upto 0.5 µg/ml. The degradation of diperodon enantiomers was studied in serum by an in vitro methodand the experimental rate constants were determined.
Key words:
