The Use of NMR Detection of LC in Carotenoid Analysis

Bioactive compounds, such as carotenoids have strong antioxidative properties and are used as ef - cient radical scavengers. In some natural sources several carotenoid isomers can be found, which differ in their biochemical activities such as bioavailability or antioxidation potency. Knowing the structure and concentration of each stereoisomer is crucial for an understanding of the effectiveness of carotenoids in vivo.
