General description

Polyphosphoric acid (PPA) is an inorganic acid. Galangin-KMnO4-PPA system has been employed for the determination of tryptophan. It participates in the Skraup reaction. It is widely employed reagent for the alkylation and acylation reactions of aromatic and alkenic compounds.

A novel galangin-potassium permanganate (KMnO4)-polyphosphoric acid (PPA) system was found to have an outstanding response to tryptophan (Trp). Trp determination using this KMnO4 -PPA system was enhanced significantly in the presence of galangin. A highly sensitive flow-injection chemiluminescence (CL) method
