Enantioseparation of methamidophos by HPLC-UV using polysaccharide chiral stationary phase
(Elsevier B.V., 2010-07-17)
Determination of Catechin Diastereomers from the Leaves of Byrsonima species Using Chiral HPLC-PAD-CD
When catechins are found in plant extracts, they are almost always identified as catechin and/or epicatechin probably due to stereoselectivity of the enzymes involved in the biosynthesis of these substances. However, the ...
Enantioselective analysis of oxybutynin and N-desethyloxybutynin with application to an in vitro biotransformation study
(ELSEVIER SCIENCE BV, 2008)
An enantioselective method using liquid-phase microextraction (LPME) followed by HPLC analysis was developed for the determination of oxybutynin (OXY) and its major metabolite N-desethyloxybutynin (DEO) in rat liver ...
Stereoselective determination of midodrine and desglymidodrine in culture medium: Application to a biotransformation study employing endophytic fungi
(WILEY-V C H VERLAG GMBH, 2010)
A CE method was developed and validated for the stereoselective determination of midodrine and desglymidodrine in Czapek culture medium to be applied to a stereoselective biotransformation study employing endophytic fungi. ...
Enantioselective Analysis of Fluoxetine and Norfluoxetine by LC in Culture Medium for Application in Biotransformation Studies Employing Fungi
A liquid chromatography method is described for the analysis of fluoxetine and norfluoxetine enantiomers in fungi cultures. The analytes were separated simultaneously by LC employing a serial system. The resolution was ...
