  • Simple process to produce and separate water soluble and oil soluble antioxidative flavoring compositions from labiatae herbs using green solvents
    Patent number: 9376351
    Abstract: Processes for preparing water soluble and oil soluble antioxidant compositions extracted together from Labiatae herbs in a single extraction using an alcohol and water solvent, followed by a simple, yet effective purification step that allows the separation of the water soluble antioxidative fractions containing mainly rosmarinic acid from antioxidative fractions containing mainly carnosic acid and carnosol, without cumbersome acid/base partitioning steps.

  • Extracts of Asteraceae containing reduced levels of phototoxic thiophene derivatives and methods for preparing same
    Publication number: 20060182826
    Abstract: The present invention is concerned with extracts of Asteraceae containing reduced levels of phototoxic thiophene derivatives. Novel methods that may result in about a fifty-fold to hundred-fold or more reduction of phototoxic thiophene levels in a commercially attractive process is described. The Asteraceae plant extracts comprising xanthophylls with reduced levels of thiophene derivatives may be used in applications that include nutritional supplements and cosmetics.
