المستخلص

Artificial colors have a harmful effect on human health, as they cause some diseases, including but not limited to liver and kidney attacks. Therefore, they can be replaced with natural colors from some plants. Some pigments are extracted from these plants, for example chlorophyll pigments in spinach and beta carotene pigments in carrots, using one of the appropriate chemical separation methods using the appropriate solvent. For example, when extracting chlorophyll pigments from the spinach plant, the separation method (simple distillation) is used, using the solvent (isopropyl alcohol), and when separating carotene pigments, the (separation funnel) method is used, using solvents (Ethanol, petroleum ether)
As well as the separation of betalain pigments from beets using the method (separation
aqueous) using a polar solvent (water)
