Rosemary extract is obtained from ground dried leaves of Rosmarinus officinalis L using food-grade solvents, namely, acetone or ethanol. Solvent extraction is followed by filtration, solvent evaporation, drying and sieving to obtain a fine powder. Additional concentration and/or precipitation steps followed by deodorisation, decolourisation and standardisation using diluents and carriers of food grade quality maybe included to produce the final product. Rosemary extract is characterised by its content of phenolic diterpenes, carnosic acid and carnosol, the principal antioxidative agents. Other antioxidant components present include triterpenes and triterpenic acids. Rosemary extract is identified by the total content of carnosol and carnosic acid as a ratio of reference volatile compounds which are responsible for flavour.
