Abstract: After digested with HNO3-HClO4, Sey lecithin in the analyte was transformed to phosphate quantitatively and thuswas determined with spectrometry based on the reaction of phosphate with molybdate. The proposed analytical method wassimple, tast, of low-cost and easv-to-handle. It was suitable for the quality control of health food containg lecithin with a resultof wide linear range, good reproducibility and reasonable selectivity.
