Cancer Science & Paediatrics - Anthocyanin acts as scavenger for heavy metal ions, attack cancer cell and interacts with uric acid and urea to expel it through urine system

Anthocyanin is found mainly in red beet juice, cherry, red rose. It is red color pigment with high solubility in water. It is exchangeable similar to cation exchanger in demineralization processes of water (hetero reaction) while with the anthocyanin juice is homogenous reaction. Addition of heavy metal salt like metal nitrate (water soluble) results in sudden precipitation of metal anthocyanin and the colour of the solution disappear slowly. The pH of the solution becomes more acidic and leads to the formation of nitric acid in which the pH reaches nearly four. No precipitations shown with sodium and potassium ions while with magnesium and calcium ions need high concentration of them. Anthocyanin can be used to purify water from poisonous metals ions. Anthocyanin colour in acidic solution is shine red which gets changed to reddish green colour in basic solution and deep red colour in neutral solutions. So it is suitable indicator in acid-base reaction.
