OBJECTIVE A spectrophotometry method was developed for the determination of all Lecitin in lecitin injection. METHODS It was determined by using water as the solvent at 720nm.The condition of determination for sample was optimized. RESULT A good linearity can be found in the range of 4μg-20 μg.The average recovery was 101.3%.and RSD% was not more than 1.0. C NCLUSION The method is simple,rapid and reproducible for determination of all Lecitin in Lecitin injection.
