The standard orcinol test for estimating RNA is modified and developed as a specific method for the determination of RNA in the presence of DNA and proteins. ESTIMATION OF RNA BY (RIBOSE SUGAR) BY ORCINOL METHOD · Estimation of DNA (Deoxy Ribose) by Diphenyl Amine Method. Biochemistry and. Estimation of RNA (Orcinol method). Principle: This is a general reaction for pentoses. Acid hydrolysis of RNA releases the ribose sugar and this in the presence.
