  • Publication number: 20030096876
    Abstract: The present invention relates to a naturally obtained mixture of higher molecular weight primary aliphatic alcohols which contain 20 to 34 carbon atoms. This invention also relates to the process for obtaining the alcohol mixture by extraction and purification with organic solvents from a natural product, such as beeswax with and without saponification of the natural product. The alcohol mixture obtained from beeswax has enhanced purity and contains a mixture of alcohols having 20, 22, 24, 26, 27, 28, 30, 32 and 34 carbon atoms. The alcohol mixture is useful in pharmaceutical compositions, foodstuffs and dietary supplements and is effective for lowering cholesterol and LDL-cholesterol and increasing HDL-cholesterol levels so that it is effective in treating hypercholesterolemia.

  • Publication number: 20020098269
    Abstract: A method of preparing storage-stable, citrus-flavored compositions comprising citral or a citral derivative as the flavoring agent and a plant extract as the stabilizing agent. The plant extract inhibits the formation of p-methylacetophenone, thereby preventing the development of off-flavors and off odors and increasing the shelf life of the composition.

  • Publication number: 20020082459
    Abstract: The process of the present invention relates to the isolation and purification of both a natural mixed carotenoid product and an all-trans-&bgr;-carotene product from various different biomass sources, preferably from algae of the genus Dunaliella. More particularly, the present invention relates to a single solvent process whereby both natural and colorant products lie along the same process line. The nutritional product contains the natural array of carotenes and xanthophylls found in the plant material, while the colorant product contains primarily trans-&bgr;-carotene.

  • Patent number: 6132726
    Abstract: In general the present invention relates to a process for the removal of undesireable compounds or residues from an extract which are more polar or less polar than the desired target compound. The preferred embodiment of the present invention is a three step process and is described in detail below. The first step includes contacting a plant material that contains the desired target compound(s) with a solvent, thus producing a crude extract containing a mixture of compounds that includes, in addition to the undesireable residues, the desired target compound(s). The second step involves passing the crude extract through a series of columns containing an absorbent that retards the movement of the undesireable compounds, while allowing the desired compounds to pass. The third and final step involves drying the eluant product to achieve a final product.

  • Patent number: 5859293
    Abstract: A process for the extraction and isolation of concentrated carnosic acid from plant matter of the Labiatae family including contacting the plant matter with a water-miscible solvent to form a plant extract and adjusting the pH of the plant extract to a level between 7 and 10 while adding water in an amount sufficient to cause precipitation of impurities while retaining the carnosic acid salt in solution. The impurities are separated and the remaining aqueous solution is acidified to precipitate a highly purified carnosic acid product which is essentially odorless, flavorless and colorless.

  • Patent number: 5679806
    Abstract: The present invention relates to a process for the isolation and purification of isoflavones from a number of different biomass sources. More particularly, the present invention relates to a three-step process whereby a biomass containing isoflavones with a solvent thereby forming an extract that is subsequently fractionated using a reverse phase matrix in combination with a step gradient elution, wherein the resulting fractions eluted from the column contain specific isoflavones that are later crystallized. The purified isoflavone glycosides may then be hydrolyzed to their respective aglycone.

  • Patent number: 5412116
    Abstract: A process for the conversion of glycoside substituted taxanes to taxol and related compounds that can serve as precursors to taxol. The process includes the oxidation of glycoside substituted taxanes to convert the glycoside to the hydroxyl group. The oxidation can occur in the presence of an acid or followed by treatment with acid. Application of the process to 7-xylosyl taxol ("XT") yields taxol; application to other glycoside substituted taxanes forms compounds that can serve as precursors for taxol. The process includes the formation of certain new taxol related intermediate compounds having a hemialdal at the C-7 site on the taxane ring, which hemialdal can then be converted to taxol or taxol precursors. Since glycoside substituted taxanes are isolated with taxol from naturally occurring biomass, their conversion to taxol using the process of the present invention significantly improves the total yield of taxol from natural sources.

  • Patent number: 5244726
    Abstract: A self-hardened, high temperature-resistant, foamed composite is described. An alkali metal silicate-based matrix devoid of chemical water has dispersed therein inorganic particulates, organic particulates, or a mixture of inorganic and organic particulates, and is produced at ambient temperature by activating the silicates of an aqueous, air-entrained gel containing matrix-forming silicate, particulates, flyash, surfactant, and a pH-lowering and buffering agent.
