Abstract
and characterized them by spectrophotometry and high-performance liquid chromatography (HPLC). Additionally, the antioxidant and anti-inflammatory activities of the samples containing three forms of astaxanthin at different ratios were evaluated. The sample containing the maximum level of Ast-mE compared to those of Ast-N and Ast-dE showed the highest antioxidant and anti-inflammatory activities. We also observed the greatest increase in expression of genes related to antioxidant and anti-inflammatory effects in samples containing the highest Ast-mE. These results provide a foundation for in-depth investigation of astaxanthin and other antioxidant molecules, allowing for the development of a practical and cost-effective strategy to improve antioxidant or anti-inflammatory activities of natural extracts that can be used as dietary supplements.
