Abstract
An on-line coupled HPLC system is described for the determination of the enantiomers of diperodon in blood serum. The method involves three steps: (i) off-line preconcentration and clean-up, (ii) separation of the diperodon enantiomers from the matrix components on a reversed-phase stationary phase, and (iii) separation of the racemate from the reversed-phase column on a teicoplanin chiral stationary phase. The method is suitable for simultaneous determination of both enantiomers in serum up to 0.5 microg/ml. The degradation of diperodon enantiomers was studied in serum by an in vitro method and the experimental rate constants were determined. The enantiomeric hydrolysis rates and half-lives for diperodon in serum are different.

Abstract
The enantiomers of omeprazole and some of its analogues have been separated on a chiral stationary phase comprising trisphenylcarbamoylcellulose coated on 3-aminopropyl silica. The nature of the supporting silica has a crucial effect on the separations obtained. The racemisation half-life of omeprazole was estimated to be 1.3.10(2) h at 37 degrees C. In vitro tests on isolated gastric glands from rabbits showed that both enantiomers of omeprazole had an inhibitory effect on acid formation.
