Selenite has been found to be an active catalyst for the oxidation of sulphhydryl compounds, such as glutathione (GSH). Considering the biological importance of GSH oxidation and the implication of sulphhydryl compounds in selenium poisoning and other biological activities, more information on selenite oxidation of GSH in enzyme-free conditions is desirable. Herein, we describe glutathione and sodium selenite simply mixed in aqueous solutions.

- A new method using reversed-phase high performance liquid chromatography was developed to separate epinephrine enantiomers using a fluorescent chiral reagent for enhanced detection.
- The separation process involved a specific mobile phase composition and controlled temperature, resulting in efficient resolution of the diastereomeric compounds.
- Key performance metrics included retention times of about 30-32 minutes for each enantiomer, a linear detection range from 0.07 g/L to 0.50 g/L, and a low detection limit of 12 g/L, showcasing the method's reliability and precision.
