Popis: | The separation and chromatographic behaviour of five ACE (angiotensin converting enzyme) inhibitors and their four active metabolites were investigated by normal-phase thin-layer chromatography on silica using several mono- and binary non-aqueous solvent systems. The linear relationship between the R(M) values and the composition 0 of employed mobile phase was obtained. The hydrophobicity parameters R(M)(0) and C(0) were determined from the regression data of the plots, analogous to reversed-phase chromatography. The chromatographically obtained hydrophobicity parameters were correlated with the calculated log P values. The current results were correlated with the lipophilicity of the studied ACE inhibitors and their metabolites, previously estimated by reversed-phase chromatography. Hromatografsko razdvajanje I ponašanje pet ASE inhibitora (inhibitora angio-tenzin-konvertujućeg enzima) I njihova četiri aktivna metabolita ispitivano je metodom normalno-fazne tankoslojne hromatografije na silika-gelu primenom nekoliko jedno- I dvo-komponentnih nevodenih sistema rastvarača. Dobijena je linearna zavisnost između RM-vrednosti I koncentracije etanola u mobilnoj fazi. Na osnovu odgovarajućih regresionih podataka, po analogiji sa reverzno-faznom hromatografijom, izračunati su parametri lipofilnosti 0M R I C0. Hromatografski dobijeni parametri hidrofobnosti korelisani su sa izračunatim log P vrednostima. Takođe, 0M R -vrednosti dobijene u ovom radu korelisane su sa 0M R -vrednostima dobijenim metodom reverzno-fazne tankoslojne hromatografije. |
