Ninhydrin Test DefinitionNinhydrin test is a chemical test performed to detect the presence of ammonia, primary/secondary amines, or amino acids[1]. This test involves the addition of ninhydrin reagent to the test sample that results in the formation of deep blue color, often termed as Ruhemann’s purple, in the presence of an amino group.
Objectives of Ninhydrin Test To detect the presence of amines and amino groups in the test solution. To quantify the amino acids present in the sample. To distinguish carbohydrates from amino acids. Principle of Ninhydrin Test This assay is based on the fact that two molecules of ninhydrin (2, 2- dihydroxyindane-1, 3-dione) react with a free alpha-amino acid to produce a deep purple or blue color known as Ruhemann’s purple. In this reaction, ninhydrin acts as an oxidizing agent and causes the deamination...Ninhydrin | 水果好營養
