Abstract: A simple rapid and accurate quantitative method was established for the determination of lecithin in soybean phospholipids by HPLC.Separation was obtained by using Lichrosorb si60 column (5 m250 x 4mm ) and mobile phase of acetonitrile:methanol:water (65:21:14v/v) with flow rate of 1.8ml/min .The eluates were monitored with UV detector at 205nm.The retention time for lecithin was 4.875min .The lecithin curve was linear in the range of 0.04 0.08mg/ml with =0.9996.The average recovery rate for lecithin was 98.35%.RSD=6.94%(n=6).
