Barbituric acid and its derivatives are associated with a number of biological activities such as antibacterial, hypotensive and sedative.
Hydroxymethylfurfural (HMF): It was determined by the AOAC method (958.09) where the absorbance of a filtered honey solution, after clarification with carrez solutions and addition of p-toluidine and barbituric acid solutions, is measured at 284 and 336 nm against a blank in the maximum color intensity (3-4 minutes after the barbituric acid addition) (Bogdanov et al., 2002).
These include barbituric acid, many phenols, ethanol, and a number of pesticides to name a few.
In 100 mL round bottom flask barbituric acid/thiobarbituric acid 8a/8b (0.005 mol, 2 equivalent) and aromatic aldehydes 1-7, (0.0025 mol, 1 equivalent) was stirred in 25 mL of absolute ethanol, and catalytic amount of sodium ethoxide was added to the reaction mixture.
At stage P0, the offspring were sacrificed by decapitation, while the offspring selected at stage P14 were sacrificed by intraperitoneal injections of Tiopental (synthetic barbituric).
When determining hydroxymethylfurfural (HMF) in honey using the Winkler method, the procedure is based on the reaction of hydroxymethylfurfural with barbituric acid and p-toluidine, which results in pink, the intensity of which is measured at a wavelength of 550 nm [21, 22].

In the second tube was poured 2 ml of honey solution (10g/50 ml), 5 ml of reagent to para-toluidine (10g of para-toluidine dissolved in 50 ml of isopropanol and then 10 ml of glacial acetic acid and complete up to the mark of 100 ml with isopropanol) and 1 ml barbituric acid solution (500 mg of barbituric acid dissolved in 100 ml distilled water).
After the weighing, breast meat was collected and packaged then kept at -4[degrees]C until time course analysis of thio barbituric acid reactive substances (TBARS) and meat color scores at 0, 5, and 10 days of storage.
