Synthesis, characterization and analytical applications of chelating resin containing orcinol
The oxidation of orcinol
with potassium ferricyanide in alkaline solution produces a mixture of polymers .
RNA was quantized by treating the nucleic acid extract with orcinol
and the green colour was read at 660 nm.
1990) steroidal nucleus (Shoppee, 1964), tannin (Pearson, 1976) while pentosan was determined by first converting the pentosan into furfural and secondly by adding orcinol
iron (III) chloride mixture to furfural, from which the amount of xylan was determined from the absorbance of the furfural orcinol
reagent mixture at 630nm measured with spectrophotometer.
hydroxylase is not very substrate-specific and can also catalyze the hydroxylation of resorcinol .
RNA extract was prepared in 20% cold PCA and estimated according to the Orcinol
method, while DNA was extracted in 10% hot perchloric acid (PCA) and estimated according to diphenylamine method.
The indirect quantification of rhamnolipids was done using the orcinol
method for quantifying rhamnose (19), by mixing 1 ml of diethyl ether with 333 ml of supernatant.
Modification of anthrone, carbazole, and orcinol
reactions for quantification of monosaccharides.
