The elution order was determined by use of enantiomeric
pure standards: L-2-HG eluted at 3.5 min, and n-2-HG eluted at 4.3 min.
During the oxidation reaction the corresponding lactone was obtained in 4.5 h with moderate enantiomeric
excess (ee 37%, kinetic resolution of the initial racemic compound occurred).
Here, we sought to study some of the chiral markers present in the fruit fibre samples in order to assess whether the processing (which includes thermal treatment) affects the enantiomeric
ratio (ER), that is, with an increase of racemisation of some chiral compounds.
In addition, we discuss the implications of AM/MA concentrations and their enantiomeric
composition in authentic samples.
Likewise, other authors have studied the enantiomeric
relationship of Clenbuterol detected in biological urine samples when this substance comes from the ingestion of drugs for commercial use (Thevis et al., 2013; Parr et al., 2017; Velasco-Bejarano et al., 2017).
composition of linalol in the essential oils of Ocimum species and in commercial basil oils.
Therefore, there is a great demand for enantiomeric

pairs are non-superimposable molecules, which have the same physicochemical properties.
 reported that stereocomplexes were formed by either solution or melt blending of enantiomeric
PLA, poly(L-lactide) [i.e.
Various single enantiomeric
drugs such as levobupivacaine and ropivacaine are now being used, with concerns regarding cardiac toxicity of racemic bupivacaine.
