  • High molecular weight primary aliphatic alcohols obtained from natural products and uses thereof
    Patent number: 7141611
    Abstract: This invention provides an isolated mixture of higher molecular weight primary aliphatic alcohols having 20, 22, 24, 26, 27, 28, 30, 32 and 34 carbon atoms and having enhanced purity. This invention also provides a process for obtaining the alcohol mixture by extracting a natural product with organic solvents with or without saponification of the natural product. The alcohol mixture is useful in pharmaceutical compositions, foodstuffs and dietary supplements and is effective for lowering total cholesterol and LDL-cholesterol and increasing HDL-cholesterol levels and therefore is effective in treating hypercholesterolemia. The composition may be used to reduce the risk of coronary heart disease, to inhibit the atherosclerotic process (platelet hyperaggregability, ischemia and thrombosis), and can be used as an anti-inflammatory and anti-thrombotic agent. The composition also possesses neurotrophic properties and is useful for improving male sexual activity.

  • High molecular weight primary aliphatic alcohols obtained from natural products and uses thereof
    Patent number: 6596776
    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.

The alcohol mixture is useful in pharmaceutical compositions, foodstuffs and dietary supplements and is effective for lowering cholesterol in LDL-C levels so that it is effective in treating hypercholesterolemia. Consequently the composition may be used to reduce the risk of coronary heart disease, to inhibit the atherosclerotic process (platelet hyperaggregability, ischemia and thrombosis) and also to act as an anti-inflammatory and anti-thrombotic agent.
