  • Publication number: 20140050790
    Abstract: The invention relates to an oleogel-forming agent which comprises at least one highly dispersed triterpene. The invention also relates to an oleogel which comprises a nonpolar liquid in an amount ranging from 80% by weight to 99% by weight based on the total weight of the oleogel and an oleogel-forming agent comprising a highly dispersed triterpene in an amount ranging from 1% by weight to 20% by weight based on the total weight of the oleogel. The invention also relates to a method for producing an oleogel.

  • Patent number: 7482383
    Abstract: The invention provides a continuous process for obtaining triterpenes from plants and/or their components. The process can include continuously washing at least one of plant and plant parts in counter-current at 20° C. to 70° C. with a solvent in which the triterpenes are not soluble or only slightly soluble and continuously extracting triterpenes from the washed plant part or parts with a solvent under an increased pressure and an elevated temperature relative to the washing pressure and temperature in counter-current to form a triterpene containing solution where the plant parts are conveyed in counter-current to the solvent flow, on the basis of their different density in a pressure-tight and heatable tube and are discharged at an end of the tube opposite to the solvent discharge.
