ABSTRACT:
A process for producing a natural antioxidant from tea leaves comprising treating said tea leaves with a solvent selected from the group consisting of hot water (preferably 80.degree. C.-100.degree. C.), a 40-75% aqueous solution of methanol, a 40-75% aqueous solution of ethanol and a 30-80% aqueous solution of acetone to obtain an extract-containing solution; washing the extract-containing solution with chloroform to obtain a washed extract; combining the washed extract with an organic solvent to transfer said washed extract into said organic solvent; removing the organic solvent; and drying the resulting extract. The invention also provides the natural antioxidant produced by the aforesaid process.
