  • Process to produce stabilized carnosic acid in high concentration
    Patent number: 6335373
    Abstract: A novel process for the production of the natural antioxidant, carnosic acid, by extracting it from rosemary leaves with an aqueous solution of a lower alkyl alcohol in the presence of a water soluble acid is described. The extraction of the carnosic acid is very selective, i.e. very few other chemicals such as pro-oxidants from the plant are extracted. Furthermore, a method for the stabilization of the extracted acid from decomposition and a method of preparing the acid in high concentration are described.
