Abstract:

This study aimed at the relative bioavailability assessment of lutein esters with that of free lutein as reference in vivo. Free lutein and its esters were introduced into male SD rats by gastric administration, and then the accumulation of them in serum was assessed using C18-HPLC. It was calculated that the relative bioavailability of lutein esters is 18.55%. This result is helpful to assess the application possibility of lutein esters in foods.

Key words: lutein, lutein ester, bioavailability
