The indicative actions of the fruit extract Punica granatumL. Finally, it was confirmed that the pH variation is one of the factors that significantly affected the color of the extract of the Punica granatum L. The analytical chemistry uses synthetic indicators in what is base 4 in a relationship to verify the changes of pH according to the color variation, currently these valuation processes do not use natural indicators, generating inconveniences in the response produced by the discharge and response processes, a negative impact on the environment environment 157.

Anthocyanins to red rormed in methoxylation 4the color of anthocyanins becomes more resistant to variations in pH when found as products condensation with catechins in the saly of aldehydes 3presenting 4 different stable structures: flavonous ion, chalcone, quinoidal and pseudobase. The extract of the arils of the fruit Punica granatum L. A manual separation was carried out to ewak the arils of the pomegranate, which were disinfected with a sodium hypochlorite solution, washing at the end with abundant water.
