  • Method for the Removal of Aloin, Emodin and/or Isoemodin from Aloe Vera by Treatment with an Oxidase
    Publication number: 20070275107
    Abstract: The invention relates to a method for the removal of aloin, emodin and/or isoemodin from aloe vera gel and a method for the production of aloe vera gel with less than 5 ppm of aloin, emodin and/or isoemodin by treatment with an oxidase, whereby a manual slicing of the aloe vera leaves and losses associated with conventional production methods are avoided.

  • Amphiphilic compounds with at least two hydrophilic and at least two hydrophobic groups on a di-,oligo- or polyene base
    Patent number: 6593376
    Abstract: A process for preparing amphiphilic compounds having at least two hydrophilic and at least two hydrophobic groups by reacting an olefinic substrate having at least two double bonds with an organic hydroperoxide to form an oxirane ring, opening, the oxirane ring with an alcohol in the presence of a catalyst system comprising a molybdenum compound as a first catalyst component and a second catalyst component selected from the group consisting of boron trifluoride, alumina, 1,8-diazzabicyclo-(5.4.0)-undec-7-ene, 1,4-diazabicyclo-(2,2,2)-octane.
