Red color extraction from the St. John’s Wort plant (Hypericum perforatum) involves isolating natural pigments such as hypericin and pseudohypericin, which contribute to its characteristic reddish hues and possess therapeutic properties. The extraction process typically starts with harvesting the aerial parts of the plant, which are then dried and ground into a fine powder. Extraction is performed using solvents like ethanol, methanol, or water-alcohol mixtures under controlled temperature to maximize pigment yield while preserving their stability. Advanced methods such as ultrasound-assisted or microwave-assisted extraction may be employed to enhance efficiency and reduce extraction time. After extraction, the solution is filtered and concentrated, producing a potent red extract widely used in pharmaceuticals, cosmetics, and natural dye applications. Maintaining optimal extraction conditions is crucial to retain the color intensity and bioactive properties of the pigments.
