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].
Orcinol was first prepared by dehydroacetic acid, a conversion that involved ring-opening of the pyrone to a triketone. This early experiment helped establish the rich condensation chemistry of polyketides. It can be obtained by fusing extract of aloes with potash, followed by acidification. It undergoes O-methylation … See more Orcinol is an organic compound with the formula CH3C6H3(OH)2. It occurs in many species of lichens including Roccella tinctoria and Lecanora. Orcinol has been detected in the "toxic glue" of the ant species See more Orcinol is also found in shale oil produced from Kukersite oil shale.
