General description
α-Lipoic acid is an antioxidant which is generally present in plants, animals and many other microorganisms.[1]
Application
α-Lipoic acid has been used as a reference standard for the analysis of α-lipoic acid in human plasma by high performance liquid chromatography coupled to electron capture detector (HPLC-ECD),[1] in various food matrices[2] and dietary supplements[3] by HPLC combined with coulometric electrode array detector (CEAD) as well as electrospray ionization mass spectrometer (ESI-MS).
It may be used as a reference standard for the determination of α-lipoic acid in human urine by isocratic reversed-phase HPLC[4] and in α-lipoic acid capsules by HPLC with chemiluminescence detection.[5]
