10.2.9 Tests for ammonia or amino acids or proteins with ninhydrin
Ninhydrin, C9H6O4, indantrione hydrate, (1,2,3-indantrione monohydrate), Toxic by all routes
Ninhydrin, C9H6O4, forms characteristic blue colour on heating.
Spray the paper with a spray reagent of a 2% solution of ninhydrin in ethyl alcohol in an aerosol pack.
Ninhydrin reacts with α-amino acids to yield coloured products.
Leave the filter paper in the fume cupboard, fume hood until the spray solution is dry.
Place the filter paper in an oven at 110^oC until all the spots have developed.
Circle the spots with a pencil before they fade.
Measure from the centre of each spot to the base line.
Measure the distance the solvent has travelled at each position and calculate the Rf values for each amino acid.
Find the composition of the unknown by visual comparison of spot colours and by the relationships of Rf values.
