Ninhydrin 是一种显色分析探针，可用于氨基酸和蛋白质的定量分析。

Ninhydrin is a chromogenic analytical probe for the quantification of proteins and amino acids.

Ninhydrin is used in the amino acid analysis of proteins. Except for proline, Most amino acids can be hydrolyzed and react with ninhydrin. Ninhydrin reacts with primary and secondary amines producing a blue or purple reaction product: diketohydrindylidene-diketohydrindamine.
