WebOrcinol reacts with sialic acid in the presence of ferric ions and hydrochloric acid. The resultant chromophore formed after heating at 100°C can be extracted after cooling in isoamyl alcohol and then measured spectrophotometrically at 572 nm. However, this method suffers from interference (hexoses, pentoses, and uronic acid) [8].
