摘要
•A method for the quantification of retinyl palmitate using HPLC-UV was developed.•The HPLC method had a low LOD (0.01 µg/mL) and LOQ (0.03 µg/mL).•Vitamin A was completely extracted from simple matrices using acetone/methanol.•Vitamin A was efficiently extracted from bread and cookies with chloroform/methanol.•The newly developed procedure and the standard procedure yielded equivalent results.
