| Abstract: | The content of lutein in feed was determined by spectrophotometric method after the sample was seperated by chromatography. Silica gel taken as solid phase, carotene and lutein were eluted respectively. The detection wavelength was 474 nm, RSD of the results was 0.023%, and the uncertainty of measurement of the results was 1%-2%. |
