Red color extraction from sycamore bark involves isolating natural pigments, including tannins and flavonoids, which contribute to its rich reddish-brown hues used in dyeing and traditional medicine. The process begins with harvesting and cleaning the bark, followed by drying and grinding it into smaller particles to increase extraction efficiency. Solvent extraction using water, ethanol, or alkaline solutions is commonly employed, often enhanced by techniques such as ultrasound-assisted extraction to improve yield and preserve pigment quality. After extraction, the solution is filtered and concentrated to obtain a deep red extract suitable for use in natural dyes, cosmetics, and pharmaceutical formulations. Careful control of extraction parameters like temperature, pH, and solvent concentration is essential to maintain color vibrancy and bioactive compound integrity.
