Analytical methodology for the determination of folates and folic acid in foods


, : Analytical methodology for the determination of folates and folic acid in foods. Quimica Nova 29(5): 972-976

The aim of this work was to develop and to validate a methodology using HPLC for the simultaneous determination of folates and folic acid in foods. The limits of detection and the recovery rates for the vitamins in the certified reference materials were respectively 5 pg/mL and 94-108% for 5-MTHF, 7 pg/mL and 97-102% for THF, 30 pg/mL and 97.9-104% for 5-FTHF, 30 pg/mL and 95-107 for 10- FFA, 5 ng/mL and 97-102% for FA and 5 ng/mL and 98-103% for 10-MFA.
