| Abstract: | The samples were hydrolyzed by sulfuric acid,then the hydrolysate was filtered and diluted.The products were oxidized by chloramine T,then the red compound was obtained threugh the reaction of the product and dimethylaminobenzaldehyde,and the colorimetric assay of the compound was carried out by spectrophotometry.The method for the determination of the content of L-hydroxyoroline in leather milk has good operability,and can suit for detection in batches. |
