Article Synopsis
- - The study aimed to optimize a method for analyzing and quantifying vitamin E isomers (tocopherols and tocotrienols) in various food sources, including vegetables, herbs, eggs, vegetable oils, flaxseed, and sorghum.
- - Researchers tested different extraction and analysis conditions, settling on a method using a solvent for extraction and a specific column with a designated mobile phase for high-performance liquid chromatography (HPLC) with fluorescence detection.
- - The optimized method demonstrated excellent separation and quantification of isomers, with high recovery rates and a reliable detection range, making it faster and simpler while preserving vitamin E isomers compared to traditional methods.
